Description
The SUB-1000 model is a water-cooled Electro-Optically Q-switched laser, which have ≈ 0.5 ns pulse duration and three modes of operation: Low energy Pilot mode and High energy mode. In High Energy mode laser delivers up to 1000 mJ energy at 1064 nm wavelength and up to 500 mJ at second harmonic. Laser design comprising short cavity MO in conjunction with power amplifiers based on efficient flashlamp pumped gain modules, where ≈ 350 ps (PTP) optical jitter is welcome point for laser use in any scientific and industrial application. Due to relatively high output energy and short sub-ns pulse duration, laser delivers peak power up to 2 GW (1064 nm) and up to 1 GW (532 nm). The harmonic conversion module to green (532 nm) is available in default laser configuration.
