Fin Efficiency Design of Micro-Channel for Nd: YAG Slab Laser

The heat generated by a Slab Lasers can exceed 1,000 watts but the area available for cooling is too small. This results in localization of heat flux which makes heat dissipation a challenge in slab lasers. The Heat transfer coefficient can increase up to a very high range, which can’t be efficiently achieved by the conventional water cooling. Micro-channel coolers address this problem competently. These channels contain liquid, which transfers heat to the sink with high efficiency.The objective of this paper is to design the microchannel coolers that will be efficiently capable of removing the heat from the slab laser without causing any thermal distortion in the laser. The dimension of the slab is given as follows:-Length(l) =50mm, Width(w) =8mm and thickness(t)=2mm.
