Paper Abstract

We report an experimental study of passive mode-locking of a flash-pumped Nd:YAG laser using for the first time a non- linear polarization rotation effect in a type II crystal cut for second harmonic generation. The mode-locking regime is self-starting and produces pulses of 20 ps duration with more than 100 uj per pulse. We developed a numerical model to calculate laser pulse steady-state temporal profile as a function of group velocity mismatch between fundamental and second harmonic pulses and group velocity dispersions in the nonlinear crystal. It takes also into account on laser medium and resonator characteristics insuring perfect second order dispersion compensation during one round trip in the cavity.
