Pulsed lasing was obtained for the first time from Li/sub 2/ molecules by optical pumping with radiation from a pulsed copper vapor laser (578.2 nm, pulse repetition frequency 5 kHz). The laser transitions, with wavelengths in the range 867--907 nm, belong to the electronic A/sup 1/..sigma../sup +//sub u/--X/sup 1/..sigma../sup +//sub g/ system. With a pump power of 190 mW, an average output power of 8 mW was achieved with an efficiency for the conversion of the optical pumping energy of 7%. A number of Li/sub 2/ laser emission lines were observed in the superradiant regime.
