We have observed, for the first time to our knowledge, stimulated emission in atomic-copper vapor that is excited by a resonant tunable laser beam. One of the important and interesting results obtained in this experiment is that excitation of the /sup 2/P/sub 1/2/ level of the copper atoms generates strong amplified spontaneous emission (ASE) for both /sup 2/P/sub 1/2/--/sup 2/D/sub 3/2/ and /sup 2/P/sub 3/2/--/sup 2/D/sub 5/2/ transitions. This is the first reported direct experimental evidence observed for collisional mixing between the /sup 2/P/sub 1/2/ and /sup 2/P/sub 3/2/ levels in a copper-vapor laser. Excitation of the /sup 2/P/sub 3/2/ level induces substantially weaker ASE for the /sup 2/P/sub 1/2/--/sup 2/D/sub 3/2/ transition. In addition, we observed collision-induced ASE for both transitions over a wide range of detuning of the pump frequency. The preliminary results of the experiment are presented, and the implications of the results for high-pressure copper-vapor lasers are discussed.
