Popis:	The use of a cw diode-pumped Nd:YAG rod laser for industrial applications is investigated. The laser is pumped by water cooled high-power laser diode bars in a star-shaped transverse pumping configuration. An output power of 75 W is achieved with 240 W of pumping power, corresponding to 40% slope efficiency. Thermal lensing and birefringence of a laser rod with a diameter of 4 mm is investigated. High fundamental transverse mode and second harmonic efficiency is reported. A simple scalable concept for lasers with 10 W to 100 W output power is presented.
