Paper Abstract

A novel Nd:YAG micro slab laser amplifier is presented and experimental results for Q-switched operation are discussed. The laser crystals are directly pumped by conduction cooled laser diodes with an ISO/FDIS 17526 extrapolated standard lifetime above 30,000 h. The diffraction limited cw output power of the amplifier is 50 W. In pulsed operation, the laser shows a pulse energy of 4.65 mJ and a pulse length of 12 ns FWHM at a pulse repetition rate of 6 kHz. Beam quality has been measured to be M2 = 1.1. The beam pointing stability was 10 μrad and the pulse-to-pulse stability was 1.5% rms in a linear-polarised beam.
