Potassium Titanyle Arsenate (KTA) Crystals
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 3-4 um spectrum range than KTP.
◇ Resistant to high intensity laser radiation.
◇ Frequency doubling (SHG @1083nm-3789nm)
◇ Sum and Difference Frequency Generation (SFG)/(DFG) KTA
◇ Electro-Optical Q-switch and modulation .
