Abstract

We report an end-pumped and passive mode-locking all-solid-state laser. The laser consists of a Nd:GdVO4 crystal and a linear resonator with a semiconductor saturable absorber mirror that yield mode locking. We achieved stable continuous-wave mode locking with an 8-ps pulse duration at a 154-MHz repetition rate. The average output power was 600 mW with 4 W of pump power. To our knowledge this is the first report of the use of a Nd:GdVO4 crystal for mode locking with a semiconductor saturable absorber mirror.

摘要

我们报道了一种端面泵浦和被动锁模的全固态激光器。该激光器由一块Nd:GdVO4晶体和一个带有半导体可饱和吸收镜的线性谐振腔组成，后者实现锁模。我们实现了稳定的连续波锁模，脉冲持续时间为8皮秒，重复频率为154兆赫兹。泵浦功率为4瓦时，平均输出功率为600毫瓦。据我们所知，这是首次报道使用Nd:GdVO4晶体与半导体可饱和吸收镜进行锁模。
