We report what is to our knowledge the highest quasi-cw output power to date, 150 W, with average output power of 69 W and pulse energy of 250 mJ, for an InGaAs diode-pumped Yb:YAG laser. This performance was obtained by use of a laser head designed to be part of a master oscillator power amplifier operating at 3 kW.
