  Specialty Crystals
  
 
We are a world leader in the production of KTP and other specialty optical crystals. We also manufacture specialty crystals for passive Q-switches, High performance Optics, and other Electro-Optic applications.

KTP (KTiOPO4 - Potassium Titanyl Phosphate)
KTP can be used in applications such as Harmonic Generation for Frequency Doubling,Optical Parametric Oscillator, Electro-optic Pockels Cells and Quasi Phase Matching.    Read More
Cr4+:YAG (Yttrium Aluminum Garnet doped with Chromium)
Passive Q-switches or saturable absorbers provide high power laser pulses without electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. Cr4+:YAG is more robust than dyes or color centers and is the material of choice for 1 micron Nd lasers.     Read More
TGG (Terbium Gallium Garnet)
Terbium Gallium Garnet (TGG) is a crystal material for optical isolator devices. Optical isolator devices make use of the non-reciprocal Faraday effect in TGG. The Faraday effect is the rotation of the plane of polarization of a light beam as it is transmitted through a TGG crystal in the presence of an external magnetic field coaxial with the light.    Read More
Undoped YAG (Yttrium Aluminum Garnet)
Undoped YAG is a substrate material that can be used for both UV and IR optics. It is particularly useful for applications in the 2 - 3 µm region where glasses tend to be highly absorbent due to the strong H2O band.    Read More
Co:Spinel - Cobalt Spinel - Passive Q Switch
Passive Q-switches or saturable absorbers generate high power laser pulses without the use of electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. Co2+:Spinel (MgAI2O4) is the material of choice for the important eye-safe wavelengths near 1.5 microns. It has useful absorption that covers 1.2 to 1.6 micron laser transitions. Spinel is a hard, stable crystal that polishes well.    Read More
Neodymium: Gadolinium Vanadate (Nd:GdVO4)
Gadolinium vanadate doped with neodymium, Nd:GdVO4, is a promising material for diode pumped lasers. Like neodymium doped yttrium vanadate, the gadolinium vanadate exhibits a larger absorption and emission cross section compared to Nd:YAG.    Read More
