【摘要】 <正> 关于被动锁模钕玻璃激光器产生超短脉冲的研究,在国外已做了大量的工作。我们对超短脉冲的研究也已有多年的历史了。本工作一方面是为了产生微微秒脉冲和亚毫微秒脉冲,以供某些物理实验应用;另一方面,进一步摸索锁模规律,考察饱和吸收体锁模机理,研究各种参数对锁模的影响以及超短脉冲的性质等等。更多还原

【Abstract】 Investigation results on ultrashort pulses of a passively mode-looked Nd glass laser are presented in this article. The generation, selection and amplification of the ultrashort pulses are described in particular. The effects of dye cell, dye concentration and the transmissivity of the output mirror on mode locking have been studied. The amplification factor and the signal-to-noise ratio for pulses of 10 ps to 130 ps have been measured. Some of the experimental results on interaction between ultrashort pulses and plasma are also included.更多还原
