Abstract
A metal vapor laser discharge tube configuration for preventing accumulation of the condensed metal form interfering with the generated laser beam. A heater arrangement is positioned on the tube in an area corresponding to the area in which the metal vapor condenses within the tube. Energization of the heater when required melts the condensate thus extending the laser tube lifetime.
