Abstract
Spectra extending from 600 to 1200 nm have been generated from a Kerr-lens mode-locked Ti:sapphire laser producing 5-fs pulses. Specially designed double-chirped mirror pairs provide broadband controlled dispersion, and a second intracavity focus in a glass plate provides additional spectral broadening. These spectra are to our knowledge the broadest ever generated directly from a laser oscillator.
摘要
从产生5飞秒脉冲的克尔透镜锁模钛宝石激光器中产生了波长范围从600纳米至1200纳米的光谱。经过特殊设计的双啁啾镜对提供宽带可控色散，并且玻璃板中的第二个腔内焦点提供额外的光谱展宽。据我们所知，这些光谱是直接从激光振荡器产生的有史以来最宽的光谱。
