MNL1342
DIODE PUMPED SUB-NANOSECOND
PASSIVELY Q-SWITCHED LASER
MNL1342 series DPSS passively Q-switched sub-nanosecond lasers deliver high peak powers > 100 kW at 100 Hz repetition rate. Short laser cavity is fixed on thermo- stabilized and controlled baseplate which gives extremely stable output parameters performance. Small footprint is welcome point for integration into OEM lasers. Sub- nanosecond 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 and many 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) is also available.
