ABSTRACT:
Stackable laser array elements may be configured to absorb heat effectively from laser elements, to be efficiently repaired and/or replaced, and to be effectively tested. An assembly includes readily replaceable cells having a cavity for the passage of coolant therethrough to cool the laser elements. The cells may be constructed individually for individual testing, and then stacked together and removably secured for easy replacement. The cavities of the cells form a substantially contiguous cavity through the entire assembly for the flow of coolant into and out of the assembly. The cavities of the cells include regions and surfaces which enhance the flow of coolant to regions substantially adjacent to the laser elements for the cooling thereof to provide enhanced cooling of the laser elements in the stack of cells. The flow of the coolant is oriented vertically with respect to horizontally oriented laser elements. Various recesses and grooves in the cells permit monitoring devices such as temperature and light sensors to be positioned to collect sensor data to monitor proper operation of the assembly and the laser elements therein.
