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.
