Laser mirror with coolant fluid transfer manifold

摘要

A pressure balancing fluid transfer manifold for use with fluid cooled laser mirrors is disclosed. The manifold is adapted for connection to the inlet and outlet ports of a fluid cooled laser mirror and includes an interface fitting adapted for being fixedly connected to a mounting plate which supports the laser mirror and a housing fixedly attached to the mirror wherein the interface fitting is sealably engaged within the housing with O-ring type seals. Elongated slots within the walls of the fitting are adapted for passing coolant from the fitting to the mirror coolant distribution system. Hydraulic pressures within the fitting are decoupled from the mirrors by a vented cavity located between the end of the fitting and the mirror and the pressure forces are transmitted through the fitting to the mounting plate thereby minimizing distortion of the mirror resulting from unbalanced pressure forces. In one embodiment the interface fitting is coupled directly to the coolant distribution system within the mirror.
