Abstract
We report on the application of tunable, pulsed Ti:sapphire lasers as efficient pump sources for optical parametric oscillators. Using a 90-deg phase-matched KTP crystal, we have generated output from 1030 to 1280 nm (signal) and 2180 to 3030 nm (idler) by tuning the pump laser from 700 to 900 nm, with 49 mJ of combined signal and idler output energy at a pump level of 110 mJ. In addition, we have demonstrated degenerate optical parametric oscillator operation with a KNbO(3) crystal over the pump range of 720-818 nm and observed a 44% conversion efficiency.
