The passive mode-locking operation of an Nd ' YAG laser at 1.06 μm was achieved by using multi-quantum-well InP/InGaAsP as saturable absorber and output coupler.When the cavity length was 115 cm,a single pulse train with average pulse duration of 23 ps and energy of 7 mJ was obtained in a plane-convexity cavity.The pulse duration was 21 ps and energy was 10.5 mJ from a plane-concave cavity Nd : YAG laser.The mode-locking effect of the plane-convexity cavity and the plane-concave cavity Nd ' YAG laser was compared in the experiment.According to the structure of the sample and the passive mode-locking theory of the saturable absorber,the passive mode-locking mechanism of semiconducting multi-quantum-well InGaAsP was anylized in this paper.
