More than 100 W from a femtosecond VaryDisk system

D+G delivers a 120 W (IR) VaryDisk system. Femtosecond operation was demonstrated with pulse durations of 371 fs (FWHM) at 105 W average power.

The Figure shows a FROG-trace of the 105 W femtosecond Yb:YAG VaryDisk system; due to the short pulse duration, the pulse shows a strong pedestal, which is caused by the non-linearities within the regenerative amplifier; D+G offers other gain materials for its thin disk lasers with broader amplification spectrum in order to allow short pulse durations without pedestal.
