摘要：

Defocusing in GaAs, CdSe and InP of 25 ps pulse trains from an active-passive mode-locked flashlamp pumped Nd:YAG laser at 1.064-mu-m is investigated. The distortion of the train envelope and of the spatial beam profile induced by charge carriers created by two-photon absorption are observed at light intensities of 50-100 MW/cm2 for GaAs and CdSe and 25 MW/cm2 for InP. This different behavior is indicative of the different response of InP which is found to be not useful for passive negative feedback of mode-locked Nd:YAG lasers.
