实验上实现了半导体泵浦Yb，Na：CNGG无序晶体激光器的亚50 fs输出。在980 nm分布布拉格反射镜锥形二极管激光器泵浦下，利用半导体可饱和吸收镜（SESAM）被动锁模，分别获得了62 fs和45 fs的短孤子脉冲。超短脉冲在1061 nm的中心波长处具有~104 MHz的重复频率。据我们所知，这是第一次演示的亚50 fs脉冲从Yb 3+掺杂的CNGG型无序晶体激光器。
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 Yb3+-doped CNGG type disordered crystal lasers.
