OEM version

"MPL2510 series DPSS passively Q-switched picosecond lasers deliver high peak powers > 4 MW at 100 Hz repetition rate. Short laser cavity is fixed on hermostabilized and controlled baseplate which gives extremely stable output parameters performance. Small footprint is welcome point for integration into OEM lasers. Pulse duration of < 500 ps, high pulse energy more than 2 mJ, 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 2 MW. Optional conversion to green (532 nm) and ultraviolet (355 nm, 266 nm) is also available."
