Abstract

Computer simulation was done to determine the effect of the position of a laser diode bar on a laser diode cooler compared to the effect of changing the thickness of the top layer of copper on the laser diode cooler. The range of copper layer thicknesses tested was from 0.1mm to 1.4mm. The thicker the top layer, the better the thermal performance of the cooler up to 1.4mm. Above 1.4mm there was not measurably increased performance. The range of power input was 40W and 80W per bar. The position of the laser diode bar was only distinguishable at the 80W power level and the impractical top layer thicknesses of 0.1mm and 0.2mm, meaning that top layer thickness is much more important for improved thermal performance than the positioning of the bar on the cooler.
