摘要

基于三维模型，研究了湍流冷却剂对激光二极管棒直接对流冷却的新型激光二极管阵列（LDA）的热场和热弹性应力场（TES）分布。利用发射孔径为1 cm2的器件的精确全尺寸模型，包括三维结构的所有有源和无源元件，找到了新的DCC阵列的极限参数的精确值。对一种著名的、最先进的双面激光棒散热器和热补偿器的三明治式LDA设计中的苔丝进行了建模，并与采用DCC的LDA中的苔丝进行了比较。

Thermoelastic stresses in laser diode bars assembled into arrays with direct convective cooling

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.
