Classification: CPC H  F | IPC F  H

Claim 24:
25. A laser device comprising:
a beam emitter;
a laser package comprising (i) a thermally conductive top laser cooler disposed above and in thermal contact with the beam emitter and (ii) a thermally conductive bottom laser cooler disposed below and in thermal contact with the beam emitter;
disposed below the laser package, a thermally conductive cooling plate for conducting heat away from the laser package; and
a fastener for attaching the laser package to the cooling plate,
wherein (i) the fastener incorporates or mechanically engages with an elastic member, (ii) the fastener is configured to compress the elastic member at room temperature when the beam emitter is not operating, thereby applying a force to the laser package that is equal to a nominal force, and (iii) the elastic member is configured to be additionally compressed in response to thermally induced expansion of the laser package during operation of the beam emitter, thereby increasing the force applied to the laser package by no more than 100% of the nominal force.
