报道了在掺钛蓝宝石环形激光器中加入非线性折射率 n2 较大的 SF- 57玻璃形成腔内可控的 SPM效应 ,并引入适当的负 GVD,将脉冲宽度从 30 fs压缩至 16 fs,相应的脉冲压缩率为 4 7%。
Reported in the Ti - sapphire ring laser with nonlinear refractive index n2 larger SF - 57 glass to form the SPM effect controlled cavity and introduce the appropriate negative GVD, the pulse width from 30 fs to 16 fs, the corresponding The pulse compression ratio is 47%.
