LBO (Lithium Triborate – LiB3O5) is now the most popularly used material for Second Harmonic Generation (SHG) of 1064nm high power lasers (as a substitute to KTP) and Sum Frequency Generation (SFG) of 1064nm laser source to achieve UV light at 355nm.
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.
Potassium Titanyl Phosphate (KTiOPO4 or KTP) KTP is the most commonly used material for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly when the power density is at a low or medium level. To date, extra and intra-cavity frequency doubled Nd:lasers using KTP have become a preferred pumping source for visible dye lasers and tunable Ti:Sapphire lasers as well as their amplifiers. They are also useful green sources for many research and industry applications.
Cr²+:ZnSe saturable absorbers (SA) are ideal materials for passive Q-switches of eye-safe fiber and solid-state lasers operating in the spectral range of 1.5-2.1 μm.
Zinc Telluride is a binary chemical compound with the formula ZnTe. DIEN TECH fabricates ZnTe crystal with crystal axis <110>, which is an ideal material applied to guarantee a pulse of terahertz frequency through a nonlinear optical process called optical rectification using high-intensity light pulse of subpicosecond. The ZnTe elements DIEN TECH provides are free from twin defects.
Fe²+:ZnSe Ferrum doped zinc selenide saturable absorbers (SA) are ideal materials for passive Q-switches of solid-state lasers operating in the spectral range of 2.5-4.0 μm.
