Passive mode locking of the Yb:Sc2O3 laser is demonstrated. We investigate the laser performance with Ti:sapphire and diode-laser pumping. The laser is mode locked by use of a semiconductor saturable-absorber mirror and emits as much as 0.8 W of power in the picosecond range with a pump efficiency as high as 47%. With dispersion compensation, pulses as short as 230 fs for an average power of 0.54 W are obtained at 1044 nm. This is, to our knowledge, the first femtosecond oscillator based on an Yb-doped sesquioxide crystal.
氧化钪激光器的被动锁模。我们研究了用钛宝石和二极管激光器泵浦时的激光性能。该激光器通过使用半导体可饱和吸收镜进行锁模，在皮秒范围内发射高达0.8瓦的功率，泵浦效率高达47%。通过色散补偿，在1044纳米处获得了平均功率为0.54瓦、脉宽短至230飞秒的脉冲。据我们所知，这是基于掺镱倍半氧化物晶体的首个飞秒振荡器。
