Description
SUB21, SUB31 and SUB51 series models are passively Q-switched sub-nanosecond DPSS lasers deliver high peak powers at 100 Hz repetition rate. Short laser cavity with the fiber pumped technology 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 < 350 ps (SUB31) and
Different models operate with repetition rates up to 100 Hz and the average power ranges from 100 mW to 250 mW. Due to short pulse duration and high pulse energy laser delivers high peak power which is up to 2.8 MW. Optional conversion to green (532 nm) and ultraviolet (355 nm, 266 nm) is also available.
