Product description
APPLICATION:
● 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
ADVANTAGE:
● 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.
