Products and Services - Nonlinear Optical Crystals

GAMDAN Optics provides turn-key solutions for the following Nonlinear Optical and Laser Crystals, complete with our proprietary UV-grade super polishing for highest damage resistance and proven high damage threshold coatings.  Damage threshold and laser lifetime data may be available upon request.

  • LBOExceedingly Low Absorption, (IR absorption <10ppm/cm as measured by PCI (Photo-thermal Common-path Interferometry) adjusted with calibration factor of 3).  Highest Surface Quality (S/D of 0/0, <5A roughness).  Dimensions up to 30 x 30 x 40mm, length up to 60m (depending on aperture).  Please contact us for special dimensions.
  • KTP: 
    • KTP GTR(Grey Tracking Resistant, hydrothermally-grown) for SHG from IR to green
    • KTP OPO material: Excellent Uniformity (lambda/10) material for OPO applications 
  • BBO
    • BBO material for Q-switching: Long Z-cut dimension, 20-30mm long.  Complete free of visible defects.
    • BBO OPO material: Large dimensions, with Excellent Uniformity (lambda/10) and Great Conversion Efficiency
    • UV grade low absorption BBO for deep UV
  • Nd:YVO4 custom- growth for intra-cavity generation of IR, low absorption, with strict dopant concentration control.  Striae-free material with <0.5% dopant concentration available up to 35mm length.
