Abstract

We realized a stable Kerr-lens mode-locked operation in a Yb:YCa₄O(BO₃)₃ laser. Pulses as short as 73 fs were generated at the central wavelength of 1043 nm, with a bandwidth of 19 nm. The femtosecond oscillator operating at a repetition rate of 110 MHz delivers an average output power of 70 mW under 3 W diode pump power. To the best of our knowledge, this is the first demonstration of a pure Kerr-lens mode-locked operation in a diode-pumped Yb:YCa₄O(BO₃)₃ laser.

摘要

我们在掺镱钇钙四硼酸盐（Yb:YCa₄O(BO₃)₃）激光器中实现了稳定的克尔透镜锁模运转。在中心波长1043nm处产生了短至73飞秒的脉冲，带宽为19nm。重复频率为110MHz的飞秒振荡器在3W二极管泵浦功率下的平均输出功率为70mW。据我们所知，这是首次在二极管泵浦的Yb:YCa₄O(BO₃)₃激光器中演示纯克尔透镜锁模运转。
