Product Details

Potassium Titanyl Arsenate (KTIOAsO4), or KTA, is a nonlinear optical crystal for Optical Parametric Oscillation (OPO) application.

It has good nonlinear optical and electro-optical properties, e.g. significantly reduced absorption in band range of 2.0-5.0 um, broad angular and temperature bandwidth, low dielectric constants.

ADVANTAGES:

l  Large nonlinear optical coefficient

l  Broad temperature and spectral bandwidth

l  High damage threshold

l  Can withstand higher power density
