MNL1342 series DPSS passively

Q-switched sub-nanosecond lasers deliver highpeak powers > 100 kW at 100 Hz repetition
rate. Short laser cavity is fixed on thermostabilized and controlled baseplate which
gives extremely stable output parameters
performance. Small footprint is welcome
point for integration into OEM lasers. Subnanosecond pulse duration of < 0.5 ns,
high pulse energy more than 50 µJ, variable
repetition rate from 1 Hz to 100 Hz covers
many applications like pollution monitoring,
DNA analysis, supercontinuum generation andmany others.
Due to short pulse duration and high pulse
energy laser delivers high peak power which
is up to 100 kW. Optional conversion to green(532 nm) and ultraviolet (355 nm, 266 nm) isalso available.
