Applications

Optical Parametric Oscillation (OPO); Frequency Doubling (SHG @1083nm-3789nm); Sum and Difference Frequency Generation (SFG)/(DFG); Electro-Optical Q-switch and modulation for Optical waveguides

Key Features

Large nonlinear optical and electro-optical coefficients; Wide angular bandwidth and small walk-off angle; Broad temperature and spectral bandwidth; Low dielectric constants, loss tangent and ionic conductivities (much less than that of KTP); High damage threshold; Lower absorption in the 3-4 µm spectrum range than KTP. Highly resistant to high intensity laser radiation. Optical Property
