Optimizing the micro channel heat sinks leads to decreased thermal resistance and decreased pressure drop. In the presentation the steps to ten times reduced pressure drop and optical power output of the diode lasers of over 100 Watts will be described.encopper heat sinkheat sinkhigh power laser diodelaser arraylaser diodemicro channelmicro channel heat sinkmicro coolermicro cooling system621conference paper
