Nuclear lasing of /sup 3/He-Ar at 2300-torr total pressure with a thermal neutron flux of 4.3 x 10/sup 16/ n/cm/sup 2/ sec has resulted in a lasing output power of 1012 W. A multiple-path laser cavity was used with seven passes through the laser medium which was pumped by the /sup 3/He(n,p)/sup 3/H nuclear reaction. The thermal neutron lasing threshold flux was 1 x 10/sup 16/ n/cm/sup 2/ sec. At 600-torr /sup 3/He-(2%)Ar, the threshold flux was 4.7 x 10/sup 15/ n/cm/sup 2/ sec. This represents the highest-power, largest-volume nuclear laser to date.
