High-power continuous-wave diode-pumped Nd:YAlO_(3) laser that emits on low-gain 1378- and 1385-nm transitions

摘要

Efficient operation of a diode-pumped Nd:YAlO_(3) laser on low-gain 1378- and 1385-nm transitions is reported for the first time, to our knowledge. A three-mirror folded cavity with a prism yielded a cw laser output power of 800 mW for an absorbed pump power of 11 W. The laser beam was TEM_(00). We managed to eliminate the instabilities in the output power by purging the cavity of water vapor with nitrogen.
