Abstract

This paper presents the highest average power passively Q-switched Nd:vanadate laser, to the best of our knowledge. A maximum average output power greater than 11W was demonstrated using a Nd:YVO4 bounce geometry laser operating at 1064nm in TEM00 mode, with a spatially stigmatic design. Pulse energies greater than 58µJ and peak powers in excess of 1.9kW were obtained; the maximum repetition rate recorded was 190kHz, close to the upper limit achievable with Cr4+:YAG saturable absorbers.
