Intense Laser Adaptive Optics

A unique deformable mirror

A dedicated solution for ultra-intense and ultra-fast lasers

ILAO™ (Intense Laser Adaptive Optics) is themost advanced deformable mirror available
that is speciﬁcally designed for today’s ultraintense and ultra-fast lasers. Based on
patented technology developed by ISP System,ILAO operates using mechanical actuators withastatic ﬂoating heads that perform wavefront
shaping with nanometric precision. Dependingon the type of laser, users can choose from
replaceable dielectric or metallic reﬂective
surfaces up to 350 mm in diameter.

ILAO is the wavefront correction element of the full-featured adaptive-optics solutions
that Imagine Optic provides for ultra-intense and ultra-fast lasers. When combinedwith a HASO3 wavefront sensor and our CASAO command & control software, youhave a turnkey solution, where each element works together seamlessly via one
ergonomic interface. For even more precision and intensity at the focal spot, the allnew PhaRAO corrects for aberrations at the end of the ampliﬁcation chain.

What’s more, once the optimal mirror shape has
been achieved, power is no longer necessary tomaintain ILAO’s form. The fact that the mirror
no longer dissipates any energy or heat fromits interior ensures that its high optical quality
surface (<10 nm rms) maintains a perfectly
stable form over time and minimizes the risk ofunwanted hotspots.

With their simultaneous, yet independent, measurementof both phase and intensity, HASO wavefront sensors
provide up to Ȝ/100 accuracy with resolutions ranging
from 32 x 40 to 128 x 128 true absolute measurement
points. With HASO3, users don’t have to compromise
dynamic range for accuracy thanks to HASO3’s patented
microlens technology. Even more, certain models connect
via Giga-Ethernet, enabling them to be placed at large
distances from the control room.

CASAO adaptive-optics command & control
software provides a unique and ergonomic
interface that allows you to acquire detailed
wavefront measurements for analysis,
precisely control your wavefront correction
device, and perform instrument diagnostics.
As an added beneﬁt for intense lasers,
CASAO has built in, user deﬁnable, security
protocols that enable you to set your system
to automatically shut down in the case of a
suspicious, potentially damaging, situation.

PhaRAO is a wavefront-sensorless solution
for correcting aberrations of focalization
systems at the end of the ampliﬁcation chain.
By using the image acquired by a diagnostic
camera, it employs complex algorithms tocalculate the ideal deformable mirror form
that corrects for end-of-chain aberrations
and increases intensity in the focal spot.
