Welcome to OPIC 2020

Shuji Sakabe

OPIC 2020 Organizing Committee
Professor, Kyoto University

Fumihiko Kannari

Chair
OPIC 2020 Steering Committee
Professor, Keio University

The Optics and Photonics International Council (Japan) has organized the Optics and Photonics International
Congress (OPIC) and the Optics and Photonics International Exhibition (OPIE) annually at Pacifico Yokohama since2012. OPIC historically includes more than 10 technical conferences in related technology areas. It is extremely importantto hold different optics-related technical conferences at one place at the same time because laser sources, light detection,and light active control are common elemental technologies. Sharing the supply and demand from each technicalconference accelerates the development of these technologies and their applications.
OPIC is now one of the largest international conferences, suitable to efficiently attract the latest advanced science andtechnology information of optics, photonics, and their applications. OPIC 2020 is co-chaired by Yoshiaki Kato (Graduate
School for the Creation of New Photonics Industries), Christopher P. J. Barty (University of California, Irvine), Reinhart
Poprawe (Fraunhofer Institute for Laser Technology), and Ruxin Li (Shanghai Institute of Optics and Fine Mechanics,
Chinese Academy of Sciences).
OPIC 2020 was originally composed of 15 technical professional conferences, covering the fields of lasers and photon
sources, biomedical imaging and sensing, high energy density science, nano-photonics and nano-optoelectronics, IoT
enabling sensing/network/AI, laser display and lighting, light-emitting devices and their industrial applications, laser andsynchrotron radiation combination experiment, laser solutions for space and the earth, optical manipulation and structured
materials, optical technology and measurement for industrial applications, optical wireless and fiber power transmission,laser damage, smart laser processing, and x-ray optics and applications.
However, due to the rapid world-wide spreading of the new coronavirus (COVID-2019), we decided to hold OPIC
2020 not as an in-person conference as originally planned, but as an online virtual conference. The health and safety of
OPIC conference attendees is always of primary importance. Although we cannot communicate directly as at in-person
meetings, this online conference has several advantages: you can focus on the specific presentations you are interested inon your pc, you can attend presentations at various sessions without conflict or overlap in parallel session timing.
The steering committee of each technical professional conference intensively discussed to find the best adjusted
scheme for the community supporting the conference. Unfortunately, four technical professional conferences decided tocancel their meeting. OPIE, one of the largest exhibitions in Japan specializing in photonics, also gave up to hold in thisyear was also forced to cancel. But, the rest of eleven remaining OPIC 2020 conferences have decided to hold an online
virtual meeting.
With a few exceptions, all presentation videos will be uploaded to YouTube and Youku at “unlisted” property during
the week of OPIC 2020 (during 9:00 of April 20 – 17:00 of April 24, Japan time). All registered participants will have accessto all archives from the registration accounts page, including presentations at conferences other than the one they registeredfor (more on this later). The presentation archives are protected from downloading but all registered participants canaccess and download the full abstracts of OPIC 2020.
The OPIC 2020 plenary session will also be held with video presentation. Two prominent scientists are invited to givethe plenary lectures: Prof. Gérard Mourou (École Polytechnique, recipient of 2018 Nobel Prize in Physics) and Dr. Berthold
Schmidt (CTO, TRUMPF Lasertechnik GmbH).
The organizer would like to thank all who have submitted the papers and also the invited speakers who have agreed tomake presentations at OPIC 2020. Since we made every effort to make this conference very useful to all participants, wehope you will bring back many fruits from OPIC 2020 and strengthen our communication in spite of this difficult situation.
The OPI Council sincerely appreciates the authorized support of the Ministry of Education, Culture, Sports, Scienceand Technology (MEXT), the Ministry of Economics, Trade and Industry (METI), the Ministry of Agriculture, Forest andFishery (MAFF), the Ministry of Health, Labor and Welfare (WHLW), the Ministry of Land, Infrastructure, Transport andTourism (MLIT), and Keidanren (Japan Business Federation). We appreciate cooperation with the societies and agencies
in Japan, USA, Germany, Taiwan, and Korea. Also, we would like to thank the founding organizations and companies fortheir strong support of OPIC 2020.
The organizer hope that we will get together again in OPIC 2021 and celebrate overcoming the virus infection.

In combination with CPA [6] highest laser
intensities can be generated enabling e.g. nonlinear
absorption even in transparent materials like glass or
sapphire. Special optical elements such as TRUMPF’s
TOP Cleave or TOP Weld optics yield laser intensity
profiles with a constant intensity along the propagation
line. In combination with USP lasers this enables glass
separation (I ~ 1013 W/cm2) with a thickness of up to 12
mm in a single shot [7] or direct welding of glass or

When reaching pulse energies of 700 mJ with 900 fs
pulse duration, intensity levels are already achieved far
beyond what is required for micro material processing.
However, these high power USP lasers enable new
exciting applications such as the control of lightning[9], by opening a plasma channel of higher electricalconductivity in air to control the propagation ofelectrical discharge. Targeting lasers with even higher
intensities e.g. > 500 mJ at 30 fs pulse duration, so called

feasible.

We are delighted to welcome you to the 9th Advanced Lasers and Photon Sources Conference (ALPS 2020), Japan.
The ALPS aims to provide a fruitful opportunity to exchange information and discuss recent progress in lasers andphoton sources, and related basic research and industrial applications. The ALPS conference is organized as part of
the OPTICS & PHOTONICS International Congress (OPIC 2020), which consists of fifteen optics-related scientificconferences. In the ALPS 2020, we will have 25 excellent invited talks and more than 100 contributed papers, which covernovel optical materials, high average power lasers, high peak power lasers, novel solid-state, fiber, diode lasers, shorter
wavelength light sources, terahertz devices, novel optical devices, optical frequency combs, quantum optics, and theirapplications.
The world is in harsh trouble because of the COVID-19, but we are holding ALPS 2020 in a new form: an online
conference. We encourage you to actively participate in all aspects of the Congress and hope that you will find theseinteractions to be beneficial.
We hope that you enjoy your time at the conference.

The 6th Biomedical Imaging and Sensing Conference
BISC 2020

ConferenceSponsored by

SPIE, The International Society for Optics and Photonics

Conference Chair Toyohiko Yatagai
Center for Optical Research and Education, Utsunomiya University
On behalf of the organizing committee and program committee, it is our great pleasure that the 6-th Biomedical
Imaging and Sensing Conference in Yokohama is going to open, within the framework of the OPTICS & PHOTONICSInternational Congress (OPIC 2020). Unfortunately, due to spreading of COVID-19, the conference this year is performed
as a digital conference via an internet system.
In biomedical optics and photonics, optical tools are employed for understanding and treatment of diseases, from thecellular level to macroscopic applications. At the cellular level, highly precise laser applications allows the manipulation,
operation or stimulation of cells, even in living organisms or animals. Optical microscopy has been revolutionized by athorough understanding of the different markers and their switching behavior. marker-free microscopy, like SHG or THGmicroscopy is spreading into multiple biological and clinical imaging applications. OCT is continuously broadening its
clinical applicability by even higher resolution, higher speed and more compact and the use of Doppler and polarization
sensitivity for functional imaging.
In the field of optics and photonics, biomedical imaging and sensing areas are most quickly progressing and expanding.
Techniques developed in these areas could bring us great steps in advances of physical, engineering and biologicalknowledge as well as optics and photonics technology. This Conference aims at covering several aspects from thefundamental studies at cellular level to clinical applications of various optical technologies.
Finally we hope the 6-th Biomedical Imaging and Sensing Conference contributes to the progress in this field and wehope you enjoy fruitful discussions in the Conference.

OMC 2020 Conference Chair Takashige Omatsu
Chiba Univ.

Since the first demonstration of an optical tweezer based on optical radiation forces (scattering and gradient forces)
created by a tightly focused laser beam, optical tweezers have been widely investigated in a variety of research fields,
including biology, physics, and chemistry. In fact, Dr. A. Ashkin was awarded Nobel Prize in Physics, for contributing to apioneering work of optical manipulation, 2018.
Conventional optical tweezers have been mostly adopted to dielectric particles with a dimension range from hundredsof nanometers to tens of micrometers. However, they do not always enable us to efficiently trap nanosacle-sized dielectric
particles as well as metallic particles.
In recent years, plasmonic tweezers based on enhanced radiation forces owing to surface plasmon polaritons inmetallic nanostructures have been successfully demonstrated to efficiently trap and manipulate both nanosacle-sized
dielectric and metallic particles.
Also, structured lights, such as higher order Laguerre-Gaussian and Bessel beams carry optical angular momenta, andthey provide unique tweezing abilities, for instance, for inducing an orbital motion of the trapped particles without
employing mechanical systems.
Since 2014, the OMC has been successfully collecting more than 80 participants from home and abroad. The OMC
2020 conference aims to present and discuss up-to-date scientific subjects, new technologies, and applications related to
the fields of optical and plasmonic tweezers, the manipulation of nanostructures, structured optical fields and their satellite
topics.
We hope that this conference will also facilitate scientific and professional networking as well as scientific inspiration
through discussions.

Maximizing peak laser intensity puts steep
demands on focal spot size, which increases
facility cost & complexity. Compoundparabolic concentrator (CPC) targets relax
focusing requirements while achieving
results consistent with high effective
intensities. We measured the performance of
CPC targets with laser conditions from 0.1– 40 ps, 100 – 2600 J, and F/#’s of 10 – 60.
CPC targets produced ~10x higher

A dense plasma ablation happens in thecontinuous plasma heating with a relativistic
multi-picosecond laser light. The ablation
plasma has an extremely pressure beyond
the laser photon pressure, thus thelaser-plasma interface is pushed backward
resulting the fast electron energy reduction.

Achieving low fuel entropy in layered
implosions on the National Ignition
Facility
Brian Michael Haines
Los Alamos National Laboratory
Achieving ignition with 2MJ of laser energy
requires reducing the fuel layer entropy toincrease energy coupling to the hot spot. We
use simulations of implosions that resolve
mixing to study the impact of instability
growth on implosion adiabat, which isincreased by up to 30% over the design
adiabat. The modeling of these processes
brings the areal density inferred bysimulation in line with experimental
measurements. The results imply smoothercapsules are needed.

This paper will present the mechanism bywhich the sloshing high energy electrons are
confined in the laser focal spot of the thinfoil. The confinement is due to the random
walk of high energy electrons scattered by
the electromagnetic fluctuations in the thinfoil. The lateral expansion velocity of highenergy electrons is highly suppressed by the
random scattering.

study on the impact of a gas atmosphere on
the collision of two counter propagatingplasmas. We observe the interpenetration of
the two plasma in the vacuum while they
stay separated once helium is added. The
presence of helium is enough to transition
from an interpenetrating regime to a regime

which used two collimated plasma jets
propagating collinearly to a strong (20 T)
magnetic field and which are made to collide
within a low-density ambient gas. The
collision triggers the heating of the colliding
plasmas, inducing fast radial expansion ofplasma into the ambient. The envelope atthe edge of the expansion is unstable to theRayleigh-Taylor instability, which drives thegrowth of plasma fingers within the ambient.
