Description
The SUB300T series model is a water-cooled Electro-Optically Q-switched DPSS laser, which have electronically tunable pulse duration ranging 350…2200 ps. Laser delivers up to 300 mJ energy at 1064nm wavelengths at 50 Hz repetition rate. Laser design comprising short cavity MO-PA in conjunction with power amplifiers based on long lasting VCSEL pump technology. The laser design assures extremely stable output parameters performance, where ≤ 200 ps optical jitter is welcome point for laser use in any scientific and industrial application. Due to relatively high output energy, good M2 ≤ 1.3 parameter and short sub-ns pulse duration, laser delivers peak power up to 857 MW (1064 nm), 457 MW (532 nm) and 257 MW (355nm). The harmonic conversion module to green (532 nm) and ultraviolet (355 nm) are available in default laser configuration.
