摘要:

Continuous‐wave laser oscillation has been observed in pure helium at wavelengths of 95.8 and 216.3 &mgr; corresponding to the 31P→ 31Dand 41P→ 41Dtransitions, respectively. Study of the excitation mechanism of the laser levels permits calculation of gain and output power starting from first principles.
