Abstract

Based on 3D models, the distributions of thermal fields and thermoelastic stress fields (TES) in the new laser diode array (LDA) with direct convective cooling (DCC) of laser diode bars (LDBs) by turbulent coolant flow have been studied. Refined values of the limiting parameters of the new DCC array were found using the precise full-scale model of the device with 1 cm² emitting aperture, including all active and passive elements of the 3D construction. Modeling of the TESs in a well-known, most advanced sandwich-type LDA design with double-sided laser bar heat sink and thermal compensator application was also performed and compared with the TESs in the LDA with DCC.
