We experimentally demonstrated a diode-pumped sub-50 fs Yb,Na:CNGG disordered crystal laser. Pumped by a 980 nm distributed Bragg-reflector tapered diode laser and passively mode-locked with a semiconductor saturable absorber mirror (SESAM), soliton pulses as short as 62 fs and 45 fs were obtained without and with external compression, respectively. The ultrashort pulses had a repetition rate of ~104 MHz at the central wavelength of 1061 nm. To the best of our knowledge, this is the first demonstration of sub-50 fs pulses from the Yb-doped CNGG type disordered crystal lasers.
我们通过实验证明了一种二极管泵浦的亚50飞秒Yb,Na:CNGG无序晶体激光器。由980 nm分布布拉格反射器锥形二极管激光器泵浦,并通过半导体可饱和吸收镜(SESAM)进行被动锁模,分别在无外部压缩和有外部压缩的情况下获得了短至62飞秒和45飞秒的孤子脉冲。这些超短脉冲在1061 nm的中心波长处具有约104 MHz的重复频率。据我们所知,这是首次从掺Yb的CNGG型无序晶体激光器中产生亚50飞秒脉冲的演示。
