Gas circulation type gas laser apparatus and method of operating the same.

摘要

The invention relates to a gas laser using a laser gas medium while circulating and purifying the laser gas medium. An object of the invention is to provide a gas laser apparatus operating method and a gas laser apparatus in which it is easy to keep laser output power constant for a long time. Disclosed is a method for performing laser oscillation while circulating a laser gas medium containing a rare gas, in which a gas which is to be solidified at a trap temperature is preliminarily attached to a low temperature trap (1) containing a filler (2) so as to be solidified, and then the solidified gas is brought into contact with the laser gas medium. <IMAGE> <IMAGE>
