Paper Abstract

This paper presents results of the numerical modeling of a passively Q-switched intracavity harmonic generator as a source for laser micromachining. The model is based on the system of coupled rate equations for the active laser medium, passive Q-switching element, laser mode and mode of the generated harmonic. Main features of the system behavior (pulse shape and duration, repetition rate) were investigated numerically. Numerical investigations of the interaction of laser pulses generated by this system with metal target with focus on the laser pulse width dependence are presented.
