An extended application of the magnetron sputtering discharge is descr
ibed. The discharge, called a magnetically confined discharge in the e
xperiments, is pumped in a pulse mode to produce and excite copper vap
or atoms for laser operation. Copper atom densities adequate for laser
action (similar to 10(14) cm(-3)) are obtained in the discharge at te
mperatures below 400 K. Laser operation is expected in the experimenta
l apparatus with fast-rise pulse pumping. (C) 1996 American Institute
