ABSTRACT:
A gas laser includes a housing containing a lasing gas. Means are provided for electrically exciting the gas including a cathode mounted at one end of the housing and an anode mounted at the other end. The temperature of the anode is monitored and a control signal is generated which is indicative of the temperature that is measured. An automatic gas supply apparatus is activated to vary the gas pressure in the housing in response to the control signal. Additionally, the temperature that is measured may be normalized to counteract the effects of the ambient temperature of the anode.
