Abstract
A BBO-I noncollinear optical-parametric chirped-pulse amplifier pumped by a Q-switched and frequency-doubled Nd:YAG laser has been demonstrated. At an optimal pump-signal angle, the temporally stretched chirped signal pulses with bandwidth of 36 nm (FWHM) were amplified without any distortion in spectrum. The gain bandwidth was very sensitive to the pump-signal angle. Variation of this angle by about 1.5 mrad may significantly reduce the amplified bandwidth and result in a significant distortion in the amplified spectrum.
