A process for manufacturing helium metal vapor laser tubes having an extended life characteristic. Three main areas of processing are presented which extend the life expectancy of a helium metal vapor laser tube. The first area of processing is directed to a time bake under vacuum of the tube to be used; the second is directed to the melting of the metal in an argon atmosphere; and the third area is directed to a final burn-in procedure of the helium metal vapor laser using the manufactured helium metal vapor tube.
