摘要：

We present our recent developments in high-power, high-efficiency cryogenic Yb:YAG laser systems. Specifically, we will discuss our 2.3-kW master oscillator power amplifier (MOPA) which has shown optical wall-plug efficiencies above 30-% (diode-driver input to optical output). This laser system has been operated for long run times with continuous wave and pulsed output formats. The beam quality factor, M-2, of the MOPA has been measured to be less than 2 and it is currently limited by the master oscillator. We are working to improve the device's beam quality and output power. In addition, we have demonstrated an all-cryogenic Yb:YAG laser that produced 29 W of optical power. Use of cryogenic diode laser pumps represents our next step towards achieving greater than 50% efficient high-power laser systems.
