Abstract
A high-power picosecond optical parametric oscillator (OPO) based on a 47-mm periodically poled lithium niobate crystal is described. More than 12 W of total average power—almost 8 W of signal power at and more than 4 W of idler radiation at —is simultaneously extracted from less than 18 W of average pump power. The OPO is synchronously pumped by 80-ps (FWHM) cw mode-locked pulses at , and its output is tunable from 1.7 to . Nearly transform-limited signal pulses are obtained following the introduction of two intracavity etalons.
