Abstract
A method and apparatus for pumping a coolant through a laser cavity to cool the laser. The apparatus has a titanium housing and a casing containing a rotatable titanium hollow shaft. A titanium impeller is located at one end of the shaft within the housing and rotates with the shaft to pump the fluid through a laser. Disposed within casing and attached to the shaft are a plurality of permanent magnets. External to the casing are stator windings through which current flows to create a magnetic field that rotates the permanent magnets, shaft and impeller. When the impeller is rotated, the coolant is passed through the housing and to the laser. The impeller also forces the fluid passing through the shaft and into the casing to cool and lubricate the pump. The magnets are encased in a titanium sleeve attached to the titanium shaft to prevent the coolant from contacting with the magnets.
