摘要：

We have used lithium borate crystals, pumped by 18 ps laser pulses at 0.355-mu-m, as efficient optical parametric generator and amplifier of tunable, high-power picosecond pulses in the visible and near-infrared. This angle-tuned parametric device has a remarkably wide tuning range from 0.403 to 2.58-mu-m with a maximum pump-to-signal conversion of 28% around 0.425-mu-m We investigate the influence of the pump intensity on the bandwidth of the tunable output. The duration of signal and idler pulses is 11-12 ps. No bulk or surface damage was observed for pump intensities up to 5 GW/cm2.
