Diode-pumped CW and passively Q-switched lasers of Nd:GdLuAG mixed garnet at 1123 nm.

Diode-pumped CW and passively Q -switched lasers of Nd:GdLuAG mixed garnet at 1123 nm were demonstrated. The maximum average output power of CW operation was 4.13 W. For Q -switched operation, the average output power was 800 mW, the corresponding single pulse energy was 133.8 µJ. The Nd:GdLuAG laser emitting at 1123 nm was obtained for the first time to the best of our knowledge, which proves that the Nd:GdLuAG mixed garnet has a better ability of energy storage than Nd:YAG in 1123 nm oscillation.
