ABSTRACT:
A method of manufacturing gas lasers, such as He-Ne lasers or Ar lasers characterized by positioning the laser housing within a vacuum chamber, evacuating the vacuum chamber to evacuate the laser housing through a filling tube provided in the housing, baking the housing, then filling the vacuum chamber with the laser gas, which enters into the laser housing through the filling tube, subsequently forming a solder closure in the end of the sealing tube, the removing the laser housing from the vacuum chamber and subsequently permanently sealing the filling tube by pinching off the solder closure to form a cold-weld seal of the tube.
