Description:
Potassium Titanyl Arsenate (KTA, KTiOAsO4) is an exceptional nonlinear optical crystal widely used in optical parametric oscillators (OPO). KTA crystals are renowned for their efficient frequency conversion capabilities, with conversion efficiencies exceeding 50%. Compared to KTP crystals, KTA offers higher nonlinear optical coefficients and electro-optic coefficients, along with a significantly reduced absorption in the 2.0-5.0 µm wavelength range. These properties make KTA an ideal choice for applications requiring reliable and tunable solid-state laser sources.
