由自锁模钛宝石激光器产生19 fs脉冲

As short as 19 fs pulses are generated from a self mode-locked Ti: sapphire laser which consistS of a Ti: sapphire rod of 5 mm long, two quartz prisms and a Xcavity configuration. The intracavity third-order dispersion is compensated properly and the shorter pulses are thus generated favorably.
