Abstract
A pulsed copper vapor laser emitting the 578.2 nm line was used as the pump source in achieving stimulated emission as a result of the electronic A1?+u?X1?+gtransitions in the Na2 molecule in the spectral range 0.765?0.804 ?. The average power of all the emission lines was 10 mW when the pulsed pump power was 150 W and the efficiency of conversion of the optical pump energy was about 3%. The pulse repetition frequency was 3.3 kHz. Violet diffuse radiation of the Na2 molecules, generated by pumping with the copper vapor laser, was observed. The superradiance regime was found for some of the lines.
