Type
           
   Your choices are...         
   Acousto-Optic       Acousto-optic crystals have changes in refractive index of the medium due to sound waves. 
   Birefringent       Birefringent crystals refractive index depends on the polarization direction of transmitted light. Birefringent crystals are commonly used to make waveplates or retarders, polarizers and prisms. 
   Electro-Optic       Electro-optic crystals are crystals which exhibit Pockels effect (linear effect) or Kerr effect (non-linear). A refractive index that changes proportionally to the electric field is the Pockels effect. A refractive index that changes proportionally to the square of the electric field is the Kerr effect. 
   Laser       Laser crystals generate laser light when an energized by an energy source. 
   Nonlinear       NLO crystals, or nonlinear crystals, generate nonlinear optical effects from lasers, electricity, magnetic fields or strain field.   
   Photorefractive       Photorefractive crystals have changes to the refractive index which is modified by spatial variations of light intensity. 
   Q-Switch       Q-switch crystals, when excited by laser light, store energy when in a saturated state and its transmission increases, reducing the resonator loss and laser pulse generated. 
   Scintillation       A scintillation crystal absorbs X-ray, gamma-rays, alpha ray and beta ray and converts some of their energy into visible light and ultraviolet (UV) photons. 
   Other / Specialty Type       The material is another specialty type of optical crystal.
