Claim 13:
14. 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
disposed between the laser package and the cooling plate, an electrically isolating barrier layer for preventing electrical conduction between the laser package and the cooling plate,
wherein:
the electrically isolating barrier layer comprises a plurality of discrete and spaced-apart areal sections with gaps therebetween;
a first region of the electrically insulating barrier material is disposed vertically beneath the beam emitter; and
a second region of the electrically insulating barrier material is not disposed vertically beneath the beam emitter.
