高能量、长锁模脉冲序列的Nd：YLF激光器研究

Study on High Energy Long Mode-Locked Pulse Train Nd: YLF Laser

首次利用ＧａＡｓ光电导开关构成的反馈回路，正、负反馈联合作用，动态控制Ｎｄ：ＹＬＦ被动锁模激光器腔内的Ｑ值，得到高能量、长序列的稳态锁模脉冲．稳态单脉冲的脉宽为４ｐｓ，能量为９μＪ，脉冲序列长１６μｓ，能量为２．５ｍＪ．

High energy long mode-locked pulse train in Nd: YLF laser was studied bydyamically control the cavity Q-factor. The total length of the mode-locked pulse trainwas about 16 μs, energy was 2. 5 mJ, single stable pulse duration was 4 ps.
