Abstract
A laser assembly includes a laser source which emits a beam transmitted through optics carried by an insulating window and thence through a pressure window supported in a thermally-insulating mount. A thermally conductive carrier ring contacts the face of the pressure window opposite the laser source and has in its outer face an annular groove receiving plural coils of an electrical resistance heating wire coupled to a current source for heating the pressure window to prevent condensation thereon.
