BENEFITS

Nanosecond Lasers

Optical parametric generator isbased on PGx03 picosecond opticalparametric amplifier systems. Fully
automatized and microprocessor
based control system ensures hands
free precise wavelength tuning.
PT403 was built without sacrificing
any parameters or reliability. The
optical design is optimized toproduce low divergence beams
with moderate linewidth (typically< 9 cm⁻¹) at approximately 20 ps pulse
duration. Featuring 1 kHz repetition
rate PT403 tuneable laser is versatile
cost-efficient tool for scientists
researching various kind of disciplines
like time resolved fluorescence,
pump-probe spectroscopy, laserinduced fluorescence, Infrared
spectroscopy and other aplications.

Nanosecond Tunable Wavelength Lasers

PT403 series laser systems integrate apicosecond 1 kHz repetition rate DPSS
pump laser and optical parametric
generator into a single housing. New
picosecond tunable wavelength laser
system provide from 210 to 2300 nm
from the one box.
Unlike other solutions in the market,
offering laser and OPO in different
units, new approach features pumplaser and OPO integrated into one
unit. That delivers almost twice
smaller footprint, shorter installation,better stability and other substantialbenefits for user.
All-in one-box solution features allcomponents placed into one compact
housing. It means better overall
stability because all potential causes
for misalignment between separate
units of pump laser and opticalparametric generator are eliminated.
To ensure reliability industry
and market tested solutions wereemployed during the build-up ofPT403.
Pump laser is based on industry“gold standard” diode pumped
Ekspla PL2210 series picosecond
mode-locked laser. Improved output
parameters and reduced maintenancecosts are achieved by employing
diode-pumped-only technology.

Picosecond Lasers

F E AT U R E S▶ Better long term stability(compared with layout where laserand OPO are in different units)▶ Higher safety – all beams are inthe box▶ Shorter installation time

▶ Almost twice smaller footprint
