Abstract


The construction of novel micro-channel cooler that allows for high packaging density of laser diode arrays is presented. Its main element is the micro-channel copper plate with micro-pipes that transport cooling liquid in the vicinity of diode laser array. The prototype series of the coolers was manufactured and tested. The experimental arrangements for investigations of thermal properties and micro-photoluminescence measurements of the devices were built. Experimental results indicate that the proposed cooler is interesting solution for high-power diode laser arrays.
