ABSTRACT:
In a gas laser including a discharge tube forming a resonant cavity, a mirror disposed at each end of the cavity, a pump, a gas source and a manometer, a first valve is connected between one end of the tube and a first of the mirrors and a second valve is connected between the other end of the tube and a second of the mirrors. Within the body of each valve is a moving element which may assume a first working position, a second position permitting mirror access and a third position for changing gas. This arrangement permits changing mirrors and/or replacing gas without exposing the cavity to atmospheric pressure and without loss of time.
