Abstract

The successful demonstrations of optical parametric oscillation in KTiOPO₄,^1,2 KTiOAsO₄,³ and CsTiOAsO₄⁴ have yielded promising results with the generation of high average powers, short pulses, and broad tunability. Another crystal in this class, RbTiOAsO₄ (RTA), is a good candidate for a OPO crystal because it has a large nonlinearity and a transparency range extending out to 5 μm. With a 800 nm Ti:sapphire pump, the RTA OPO can tune from approximately .96 μn to 5 μm as shown in Fig. 1.
