Abstract

The pumping unit consists of three 40 W CW laser diode bars mounted on modular silicon micro-channel cooled heat sinks. Two pumping units are used to assemble one pump head with a Nd:GdVO4 crystal rod of 3 mm×60 mm side-pumped. The laser with parallel-plane optical resonator emits 45 W CW laser beam with TEM01* mode pattern and line polarization. When the laser has 10 W output, the mode pattern is TEM00 with 3.9 mm diameter measured by scan method of micro-duct and near Gaussian radial intensity distribution.
