Silver Thiogallate (AgGaS2) crystal has a high non-linear coefficient, high damage threshold, and a wide transmission range. It also has low optical absorption and scattering, low wavefront distortion. Among commercially available crystals, AgGaS2 has the highest figure of merit for non-linear interactions in the near and deep infrared.

  • Large effective optical nonlinearity
  • Wide spectral and angular acceptances
  • Broad transparency range
  • High Figure of merit for non-linear interactions
  • Excellent crystal for three-wave interactions
  • Ultrashort pulse generation in mid IR range
  • Suitable for applications with CO2 laser
