KTA Nonlinear Crystal 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 µ M spectrum range than KTP.
Highly resistant to high intensity laser radiation.
KTA Nonlinear Crystal Application:
An excellent NLO crystal developed mainly for 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
