KTA Crystal


Applications and Advantages:
◇An excellent NLO crystal developed mainly for Optical Parametric Oscillation (OPO).
◇Large non linear coefficients,broad angular and temperature bandwith.
◇Low dielectric constants, low ionic conductivities.
◇Lower absorption in the 3-4µm spectrum range than KTP.
◇Resistant to high intensity laser radiation.
◇Frequency doubling (SHG @1083nm-3789nm).
◇Sum and Difference Frequency Generation (SFG)/(DFG).
◇Electro-Optical Q-switch and modulation.
