Patent ID: 7058101

Claim:
A manifold for supplying a stack of metallic, microchannel heat sinks each mounting a laser diode bar with coolant fluid, said heat sinks forming part of series-connected electrical path, comprising: an insulating body having a plurality of offset parallel planes for mounting a respective plurality of said microchannel heat sinks; said planes terminating in coolant channels in fluid communication with corresponding channels in said heat sinks; said coolant channels communicating with adjacent ones of said heat sinks and being separated from each other by at least the width of one of said heat sinks to increase the electrical resistance of said fluid path between adjacent ones of said heat sinks; and a series of stepped optical deflectors for re-arranging the laser beams emitted from the laser diode bars into vertical stack, said stepped optical deflectors comprising glass plates having a beveled edge positioned to receive the light output of a respective one of said laser diodes.
