Abstract

A diode-pumped Kerr-lens mode-locked laser generating 25 fs pulses at 1080 nm is demonstrated with an Yb³⁺-doped compositional mixed calcium aluminate crystal. The Yb:Ca(Gd,Y)AlO₄ laser, which operates at a repetition rate of 65.6 MHz via soft-aperture Kerr-lens mode-locking, is pumped by a spatially single-mode, fiber-coupled diode laser. To the best of our knowledge, this is the first Kerr-lens mode-locked laser that utilizes an Yb³⁺-doped compositional mixed calcium aluminate crystal as the gain medium.

二极管泵浦 Kerr 透镜模式锁定掺镱混合铝酸钙激光器。

利用掺杂镱3+成分的混合铝酸钙晶体，演示了一种二极管泵浦的Kerr透镜锁模激光器，它能在1080 nm波长产生25 fs脉冲。通过软孔径克尔透镜锁模技术，Yb:Ca(Gd,Y)AlO4 激光器的重复频率为 65.6 MHz，由空间单模光纤耦合二极管激光器泵浦。据我们所知，这是第一台利用掺杂镱3+成分的混合铝酸钙晶体作为增益介质的克尔透镜锁模激光器。
