We report the generation of tunable cw radiation at 1.6 μm by difference-frequency mixing in a type II phase-matched 90°-cut CsTiOAsO4 crystal, using a Kr-ion laser at 531 nm and a tunable Ti:sapphire laser as the input light sources. The output was tunable from 1.57 to 1.65 μm with a single-pass output power of 1 μW. We used doubly resonant external-cavity enhancement to generate 100 μW of output power by placing the crystal inside an optical cavity that was resonant at the frequencies of the input Ti:sapphire laser and the 1.6-μm output light.
