Crystals & Materials

Laser crystals, nonlinear crystals and optical materials for photonic systems.

Nonlinear Crystals

LBO

Lithium triborate, LBO, is a nonlinear crystal with a stated transparency range of 210–2300 nm. High-power harmonic-generation designs benefit from its damage resistance and options for noncritical phase matching.

Laser Crystals

Nd,Ce:YAG

Nd,Ce:YAG is a co-doped gain material for compact and air-cooled laser configurations. Reference rods address continuous-wave, pulsed, Q-switched and frequency-converted operation, with dopant level and finish specified ...

Laser Crystals

Nd:Glass

Nd-doped phosphate glasses N21 and N31 are gain materials for high-energy and average-power solid-state lasers. The reference data distinguish glass grades, doping concentrations and optical-quality requirements rather t...

Laser Crystals

Nd:YAG

Nd:YAG is a gain medium for continuous-wave and pulsed solid-state lasers, including Q-switched and frequency-doubled systems. Rod, slab and disc configurations combine dopant selection with optical finish and coating re...

Laser Crystals

Nd:YVO4

Nd:YVO4 is a diode-pumped laser gain material used particularly at low and medium powers. Coupling its infrared output to a nonlinear crystal enables visible or ultraviolet conversion; pump absorption and emission polari...

Nonlinear Crystals

RTP

Rubidium titanyl phosphate, RTP, is an electro-optic crystal for switching and modulation. Low switching-voltage designs and elevated repetition rates benefit from its moisture resistance and limited piezoelectric ringin...

Q-switch & Polarization Crystals

TGG

Terbium gallium garnet, TGG, is a magneto-optic material for Faraday rotators and isolators. Its stated working region is 400–1100 nm excluding 470–500 nm; the optical arrangement uses nonreciprocal polarization rotation...

Optical Materials

Undoped YAG

Undoped YAG is an isotropic optical substrate for windows and other components, distinct from doped YAG laser gain media. Its thermal conductivity, durability and broad transmission support demanding optical environments...

Laser Crystals

Yb:YAG

Yb:YAG is a diode-pumped laser gain material with broad pump absorption and a long upper-state lifetime. Reference designs compare its thermal loading and energy storage with Nd:YAG, with doping and geometry selected for...

Optical Materials

Undoped YVO4

Undoped YVO4 is a positive uniaxial birefringent material for polarization optics. Beam displacers, isolators, circulators and Glan-type components use its broad transmission and birefringence; it is distinct from Nd:YVO...

Optical Materials

ZnSe

Zinc selenide is an infrared substrate for lenses, windows and output couplers. Low absorption and careful polishing are important for high-power beams; its softness makes surface handling and coating protection signific...
