Abstract

We demonstrate the generation of 68 fs secant hyperbolic pulses at a 105 MHz repetition rate with an average power of 520 mW from a diode-pumped Yb(3+):CaGdAlO(4) mode-locked laser. A semiconductor saturable absorber allows passive mode locking, and a 15 W diode laser is used to pump directly the crystal. To our knowledge this represents the highest average power ever obtained for a sub-100 fs diode-pumped Yb-bulk laser.

摘要

我们展示了从二极管泵浦的Yb(3+):CaGdAlO(4)锁模激光器中产生重复频率为105 MHz、平均功率为520 mW的68 fs双曲正割脉冲。一个半导体可饱和吸收体实现被动锁模，并用一个15 W的二极管激光器直接泵浦晶体。据我们所知，这代表了亚100 fs二极管泵浦Yb块状激光器所获得的最高平均功率。
