Abstract

We present the first broadly tunable KNbO₃ OPO in tracking-free configuration (TFC), pumped by a flashlamp- pumped Ti:Sapphire laser. Tuning the pump laser from 733 to 841 nm yielded to an OPO tuning range from 908 nm to 1402 nm for the signal, and 2103 to 3803 nm for the idler. This range was limited by the mirror coatings, and continuous tuning should be achievable up to and beyond 400 nm. Threshold was as low as 15 MW/cm² and efficiencies up to 10% have been observed without AR-coatings on the crystal.
