本文首次报道了利用脉宽为25ns重复率为10kHz的溴化亚铜激光泵浦混有饱和吸收体DODCI的超短腔染料激光,产生出30ps光脉冲.在理论上对混入DODCI的超短腔染料激光脉冲压缩效应作了分析计算,计算结果与实验基本一致.在实验上又通过一个放大-色散系统实现对此染料激光脉冲的同步放大和调谐,并达到傅里叶变换极限.

It is reported for the first time that a 30 ps pulse is generated from the short cavity dye laser pumped by a copper bromide laser with 25 ns pulsewidth and 10 kHz-repetition rate, when mixing an amount of saturation absorber DODCI with gain medium Rh6G solution. Theoretical considerations about the pulse compression by this method are shown to agree with the experiment. Furthermore, the synchronous amplification and tuning of the dye laser pulse have been achieved with a dye amplifier-dispersion system, and reached almost Fourier-transform limit.
