摘要：

A singly resonant optical parametric oscillator is devised with type II phasematching of a KTP crystal and pumping by the second harmonic of a feedback-controlled modelocked Nd:YLF laser. Pulses of 1.5 ps duration and 50 nJ energy are generated over the tuning range 1.2-1.9 mum with time-bandwidth product < 0.5 and beam divergence < 1 mrad. Subsequent parametric amplification and down-conversion in two LiNbO3 Crystals yield single pulses of 2.1 ps and 20 muJ in the wavelength region 2.3-4.2 mum. A repetition rate of 70 Hz and rapid computer-controlled wavelength setting make the pulse generation device well suited for spectroscopic applications.
