The heat generated by a Slab Lasers can exceed1,000 watts but the area available for cooling is too small. Thisresults in localization of heat flux which makes heat dissipation achallenge in slab lasers. The Heat transfer coefficient canincrease up to a very high range, which can’t be efficientlyachieved by the conventional water cooling. Micro-channelcoolers address this problem competently. These channelscontain liquid, which transfers heat to the sink with highefficiency.The objective of this paper is to design the microchannel coolers that will be efficiently capable of removing theheat from the slab laser without causing any thermal distortion inthe laser. The dimension of the slab is given as follows:-Length(l)=50mm, Width(w) =8mm and thickness(t)=2mm.
