Potassium titanyl arsenate (KTiOAsO4, KTA) crystal KTA series

optical

Potassium titanyle arsenate (KTiOAsO4), or KTA, is a nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. Potassium titanyle arsenate (KTiOAsO4), or KTA, is a nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has good non-linear optical and electro-optical properties, e.g. significantly reduced absorption in band range of 2.0-5.0 µm, broad angular and temperature bandwidth, low dielectric constants. Primary applications of KTA crystals: ○ OPO for mid IR generation – up to 4 µm; ○ Sum and Difference Frequency Generation in mid IR range; ○ Electro-optical modulation and Q-switching; EKSMA OPTICS offers: ○ Standard KTA crystals ex-stock and crystals with size up to 15x15x30 mm under request; ○ AR and BBAR coatings for VIS-IR and mid IR ranges; ○ Standard and customized mounts and housings; Technical consulting.
