Abstract
A adaptive flow-control regulator is disclosed for use in controlling the circulation of cooling fluid through in a cooled laser mirror. The adaptive flow-control regulator utilizes a temperature-sensitive spring to control the movement of a plunger with respect to an orifice through which cooling fluid flows. Elongation of the spring is controlled by the temperature of the cooling fluid circulating around the spring. As the temperature of the coolant fluid increases from heating of the laser mirror, the spring contracts moving the plunger away from the orifice and allowing a greater volume of coolant to circulate through the mirror, thereby absorbing a greater amount of heat from the mirror structure. As the mirror is cooled by the circulating cooling fluid, the spring moves the plunger toward the orifice, thereby reducing the volume of cooling fluid circulating through the mirror's structure.
