摘要

A passively mode-locked grown-together composite YV04/Nd:YV04 crystal laser is demonstrated with a semiconductor saturable absorber mirror by 880-nm laser-diode direct pumping.Under the absorbed pump power of 24.9 W, a maximum output power of 10.5 W at the repetition rate of 77 MHz is obtained,corresponding to the optical-optical conversion efficiency of 42.1% and the slope efficiency of 53.4%.The pulse width measured is 33 ps at the output power of 10 W.
