A 6150-A He-Hg laser, pumped solely by the /sup 1/n (/sup 10/B,..cap alpha..) /sup 7/Li nuclear reaction, has been achieved using the Sandia SPRII reactor. The optimum conditions for lasing were 600 Torr total pressure with 2.5 mTorr Hg partial pressure, with a threshold for lasing of approx.10/sup 16/ n/cm/sup 2/ sec. This is the first visible-wavelength laser having nuclear energy as its only source of excitation.
