This patent describes a high-power flowing-gas laser. This laser consists of an outer housing having a sealed wall capable of withstanding an internal pressure different from atmosphere; a housing mounting for mounting the housing to a support; an optical system including a laser channel within the housing an impeller within the housing for producing a flow of gas through the laser channel; and a motor drive for driving the impeller. The laser is characterized by its inclusion of an independent mounting for mounting the optical system to the support independently of the housing mounting. This mounting thus isolates the optical system from the vibrational disturbances of the impeller and the motor drive. The independent mounting for the optical system includes legs each including a sealed leadthrough leading the respective leg through the housing wall. The sealed lead-through for each leg comprising an elastomeric boot between the respective leg and the housing wall, the outer face of each boot is disposed within the interior of the housing and the latter being subject to a sub-atmospheric pressure. The inner face of each boot is disposed exteriorly of the housing and is subject to atmospheric pressure thereby preventing the boot from buckling.
