Description
The SUB50A-700 series model is an air-cooled Electro-Optically Q-switched DPSS 1064 nm laser delivering up to 50 mJ energy and 700 ps pulse duration at 20 Hz repetition rate. Laser design is based on short laser cavity direct pumping MO and power amplifiers with the VCSEL pump technology. The know-how on thermo-stabilized structure fixed MO and AMPL elements gives extremely stable output parameters performance. Small laser form-factor and unique ≤200 ps optical jitter is welcome point for integration into OEM. Due to relatively high pulse energy, good M2 ≤ 1.3 parameter and short sub-ns pulse duration, laser delivers up to 71 MW peak power. An optional conversion module to green (532 nm) and ultraviolet (355 nm, 266 nm) is available.
