Abstract

We have demonstrated a passively mode-locked diode end-pumped all-solid-state laser, which is composed of a Nd:Gd0.5Y0.5VO4 crystal and a folded cavity with a semiconductor saturable-absorber mirror grown by metal-organic chemical-vapor deposition. Stable cw mode locking with a 3.8-ps pulse duration at a repetition rate of 112 MHz was obtained. At 13.6 W of the incident pump power, a clean mode-locked fundamental-mode average output power of 3.9 W was achieved with an overall optical-to-optical efficiency of 29.0%, and the slope efficiency was 38.1%.

摘要

我们展示了一种被动锁模二极管端面泵浦全固态激光器，它由Nd:Gd0.5Y0.5VO4晶体和一个带有通过金属有机化学气相沉积生长的半导体可饱和吸收镜的折叠腔组成。在重复频率为112 MHz时获得了脉宽为3.8 ps的稳定连续波锁模。在13.6 W的入射泵浦功率下，获得了3.9 W的干净锁模基模平均输出功率，总光光效率为29.0%，斜率效率为38.1%。
