摘要
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.
