LaserOptec specializes in the production of optical crystals, including laser crystals, nonlinear crystals, magneto-optical crystals, birefringent crystals, acousto-optical crystals, electro-optical crystals etc.
LBO crystals is an excellent nonlinear crystal.For frequency doubling(SHG),tripling(THG) of Nd:YAG,Nd:YLF,Nd:YVO4 lasers, it is one of the most useful nonlinear optical materials in ultraviolet and visible laser applications.
BBO crystal is an important nonlinear optical crystals with combination of unique optical properties.Broad transmission and phase matching ranges, large nonlinear coefficient,high damage threshold and excellent optical homogeneity provide attractive possibilities for various nonlinear optical applicatios.
KTP(KTiOPO4) crystals is the most commonly used material for frequency doubling of Nd-doped lasers, particularly at the low or medium power density.It is widely used for frequency mixing to generate Red/Green/Blue output, and for OPO and OPA to generate visible to mid-infrared tunable output. It is also used for many E-O devices such as Q-switches and E-O modulators.
Potassium Titanyle Arsenate(KTiOAsO4), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, low dielectric constants. And its low ionic conductivities result in higher damage threshold compared with KTP.
LiNbO3 Crystal is widely used as frequency doublers for wavelength >1μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices.
Compared with LiNbO3 crystal, MgO:LiNbO3 crystal exhibits its particular advantages for NCPM frequency doubling (SHG) of Nd:Lasers, mixing (SFG) and optical parametric oscillators (OPOs).
Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (KD*P ) are among the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low.
