详细介绍

The GxJ series comprises a family of 3 lasers each of which is based on a Nd:YLF oscillator and one or more Nd:Phosphate Glass amplifiers. The lasers produce near-diffraction limited single-longitudinal mode (SLM) super-gaussian radiation in the nanosecond regime from 2 to 20 J per pulse (fundamental harmonic) and from 1 to 10 J per pulse in Green pulse. Design features include a highly stable passively Q-switched linear or ring-cavity oscillator, 2-pass amplification using high energy Brillouin phase conjugation and optional frequency conversion to the second or third harmonics by DKDP. In addition to constituting highly versatile laboratory tools all GxJ lasers are rigorously designed to meet the high standards required for display and technical holography or holographic interferometry applications.

Repetitive pulsed Nd:YAG Lasers
 

The GQA/B-xJ lasers are based on a Nd:YAG oscillator and Nd:YAG amplifiers. The lasers produce near-diffraction limited single-longitudinal mode radiation in the nanosecond regime from 0.2 to 2 Joules per pulse (fundamental harmonic) and from 0.1J to 1.2J (second harmonic). Design features include a highly stable electro-optically or passively Q-switched ring-cavity oscillator, 4-pass SBS phase conjugated amplifiers using beam apodization and optional frequency conversion to the second or third harmonics. The GQA range of lasers have quasi-gaussian beam distribution. The higher energy GQB lasers have top-hat distributions.
