Abstract
A liquid stabilizing system stabilizes an internal mirror/internal resonator gas discharge laser tube assembly which has a hermetically sealed gas laser tube which includes a gas, a capillary tube, an anode, an anode end assembly, a cathode, a cathode end bell, a cathode end assembly with electrical feed-throughs for the cathode, which are coaxially disposed with a central axis, and laser mirrors, which are sealably mounted to each end of the hermetically sealed gas laser tube. The liquid stabilizing system includes a cylindrical plastic jacket and a cooling liquid. The plastic jacket has a cooling liquid inlet and a cooling liquid outlet and surrounds the hermetically sealed gas laser tube. The cylindrical cooling jacket is sealed to the hermetically sealed laser tube by O-rings which are held in place by plastic retainers. An annulus is formed between the hermetically sealed laser tube and the plastic jacket. The cooling liquid fills the annulus so that the cooling liquid is in intimate contact with all or a large portion of the surface of the hermetically sealed gas laser tube, the thermal conductivity and the specific heat capacity of the cooling liquid being sufficient to prevent misalignment of the laser mirrors under conditions of liquid convection cooling by cooling a substantial portion of the hermetically sealed gas laser tube with minimal asymmetry relative to the central axis.
