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.
