我们报告被认为是第一次演示的高功率被动锁模二极管泵浦飞秒激光器的基础上的Yb 3+：CaF 2单晶，直接泵浦的15 W的光纤耦合激光二极管。一个5-at。% Yb ~（3+）掺杂样品和棱镜进行色散补偿，获得了中心波长为1049 nm，脉宽为220 fs，平均功率为880 mW，平均功率为1.4 W，脉宽为150 fs的脉冲。激光波长可以在飞秒范围内从1040 nm调谐到1053 nm。使用啁啾镜进行色散补偿，振荡器提供了高达1.74 W的平均功率，脉冲持续时间为230 fs，对应于20 nJ的脉冲能量和85 kW的峰值功率。
We report what is believed to be the first demonstration of a high-power passively mode-locked diode-pumped femtosecond laser based on an Yb3+:CaF2 single crystal, directly pumped by a 15-W fiber-coupled laser diode. With a 5-at. % Yb3+ -doped sample and prisms for dispersion compensation we obtained pulses as short as 150 fs, with 880 mW of average power and up to 1.4-W average output power, with a pulse duration of 220 fs, centered at 1049 nm. The laser wavelength could be tuned from 1040 to 1053 nm in the femtosecond regime. Using chirped mirrors for dispersion compensation, the oscillator provided up to 1.74 W of average power, with a pulse duration of 230 fs, corresponding to a pulse energy of 20 nJ and a peak power of 85 kW.
