We demonstrate a passively mode-locked femtosecond laser based on the self-frequency-doubling crystal Yb:Ca4YO(BO3)3. The oscillator is pumped by a novel two-section distributed Bragg-reflector tapered diode-laser. Pulses as short as 46 fs and 42 fs at 1050 nm are achieved for the E//Z polarization without and with external compression, respectively. These are, to the best of our knowledge, the shortest pulses obtained from an oscillator based on Yb3+-doped bulk material.
我们展示了一种基于自倍频晶体Yb:Ca4YO(BO3)3的被动锁模飞秒激光器。该振荡器由一种新型的两段分布式布拉格反射器锥形二极管激光器泵浦。对于E//Z偏振,在没有外部压缩和有外部压缩的情况下,分别在1050 nm处获得了短至46 fs和42 fs的脉冲。据我们所知,这些是从基于掺Yb3+块状材料的振荡器中获得的最短脉冲。
