摘要: The output pulse parameters of a mode-locked Nd:YAG laser with passive negative feedback element were studied experimentally. evolution within the train was experimentally recorded using modified second harmonic generation autocorrelator. By comparing operation and without an acousto-optic modulator, we found that later there is significant increase in mode locking probability acquires temporally Gaussian symmetric shape. Further active modulator relaxation alignment tolerances range permissible dye concentrations for stable locking. It also observed width depends on saturation intensity reduces higher intensity. to reduce linearly as initial transmission reduced.
