Abstract

Recently we reported on the first observation of collisional mixing between the two upper laser levels (²P_3/2 and ²P_1/2) of the atomic copper system [1]. It was observed, for instance, that, when the lower level (²P_1/2) is excited for the yellow laser transition by a resonant laser beam at 327.4 nm, the upper level (²P_3/2) is also excited, generating a green laser beam.
