Abstract
School of Information Science & Engineering and Shandong Provincial Key Laboratory of Laser Technol ogy and Application, Shandong University, Jinan, Shandong 250100, China *Corresponding author: sasazhang@sdu.edu.cn Abstract: 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 µ J. The Nd:GdLuAG laser emitting at 1123 nm was obtained for the first time to the best of our knowledge, whic h proves that the Nd:GdLuAG mixed garnet has a better ability of energy storage than Nd:YAG in 1123 nm oscillation. Key words: 1123 nm lasers; Nd:GdLuAG mixed garnet; diode -pumped lasers.
