BRIEF COMMUNICATIONS: Calculation of the pump A calculation is reported of the pump function for the transitions responsible for the λ = 510.6 and 578.2 nm emission from a copper vapor laser. A considerable reduction in the inversion density in the case of the 510.6 nm emission due to plasma processes is predicted to occur during the emission pulse itself. In the case of the 578.2 nm emission such a reduction is much slower. <P />
