Abstract

High average power continuously pumped Nd:YAG Q-switch lasers in rod geometry were investigated. A polarization coupled resonator, intended for use in combination with polarizing switches, offers about 80% of the output power available from the equivalent resonator without a polarizer. Mechanical Q-switching by means of rotating wave plates was realized. Stable acousto-optic Q-switching of unpolarized resonators comprising one, two, or six rods was obtained within a wide range of parameters. The pulse duration varied from 150 to 1500 ns, the maximum average output power was 1.7 kW. The experimental results were well in agreement with theoretical estimations. Laser beam delivery through 600 micrometers fibers for laser materials processing was realized.
