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
10 J per pulse (fundamental harmonic). Design features include a highly stable passively Q-switched 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 applications.
