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 µm is investigated. The distortion the train envelope spatial beam profile induced by charge carriers created two-photon absorption are observed light intensities 50-100 MW/cm2 for GaAs InP. This different behavior indicative response which found to be not useful passive negative feedback lasers.
