ABSTRACT:
Thermally tuned lasers may use a resistive thermal device (RTD), sensitive to hydrogen, within a hermetic enclosure. Over time, hydrogen trapped within the enclosure or out gassed from other components within the enclosure may degrade the accuracy of the RTD. A vent comprising a hydrogen selective permeable membrane, such as palladium or a palladium alloy, provided in the enclosure vents hydrogen to mitigate damage to the RTD.
