| Abstract: | A high-efficiency and stable ps mode-locked Nd∶YAG laser that used a semiconductor saturable absorber mirror (SESAM) is reported. This SESAM is made by ourselves. The mode-locked pulse duration is narrower than 10 ps, measured by autocorrelation. The optical-optical conversion efficiency of 19% with straight cavity is attained. |
