Paper Abstract

This paper presents the results obtained in analyzing a quasi-cw flash-lamp pumped high power Nd:YAG slab laser oscillator/two stages amplifier operated in passive optical Q-switching regime using LiF:F2- crystals with an improved design. A numerical simulation method based on laser rate equation is developed for theoretical analysis of a passively Q-switched Nd:YAG slab laser system. A comparison of simulation results with experimental data is also presented to certify the viability of the developed theoretical analysis method. Laser pulses output energy of 330 mJ at a FWHM time duration of 50-75 ns and at a repetition frequency of 10 – 25 kHz (pps) are reported and numerical simulation of these experimental results are presented pointing to the output parameters stability.
