High Energy Lasers

We are manufacturing these series of high energy lasers:

  • GxJ series lasers produce single output near-diffraction limited single-longitudinal mode (SLM) super-Gaussian radiation in the nanosecond regime from 1 to 16 J per pulse (fundamental harmonics);
  • GxJ TWIN series lasers produce dual output near-diffraction limited single-longitudinal mode (SLM) super-Gaussian radiation in the nanosecond regime from 2 to 20 J per pulse (fundamental harmonics);

Output wavelengths – 1064 nm, 532 nm, 355 nm.

The GxJ series high energy single shot Hybrid Nd:YLF/Phosphate Glass lasers 

g2j_new_small

The GxJ series comprises a family of 4 lasers each of which based on a Nd:YLF oscillator and one or more Nd:Phosphate Glass amplifiers. The lasers produce near-diffraction limited single-longitudinal mode (SLM) Gaussian radiation in the nanosecond regime from 1 to 16 J per pulse (fundamental harmonic). Design features include a highly stable EO or passively Q-switched, linear telescopic or ring-cavity oscillator, 2-pass amplification using high energy Brillouin phase conjugation (SBS) 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 scientific interferometric purpose or holography applications, where smooth beam shape and long coherence length is of key importance.

The GxJ-TWIN Double Output SLM Nd:YLF/Glass LASERS

g-twin

The GxJ-TWIN series comprises a family of lasers which based on two mutually coherent and independently tunable outputs ports; basically consisting from a Nd:YLF oscillator, pre-amplifier and one pair 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). Design features include a highly stable EO or passively Q-switched ring or linear cavity oscillator, 2-pass amplification using high energy Brillouin phase conjugation (SBS) and optional frequency conversion to the second or third harmonics by DKDP. All GxJ-TWIN lasers are rigorously designed to meet the high standards required particularly for scientific interferometric or holography application purposes, where double output mutually-coherent smooth beam shape and long coherence length is of key importance.
