We report an analysis of attained output powers of laser diode bars (LDBs) and power densities of two-dimensional laser diode arrays (LDAs). A new LDA design is proposed and its thermal regime is simulated. The cw output power of the proposed LDA consisting of standard cw LDBs (output power 100 W, efficiency 50%, cavity length 2 mm) can reach 5 kW cm⁻². The parameters of a coolant flow in the microchannels of the LDA heat sink necessary to achieve such powers are calculated.

由冷却剂流直接冷却的二维激光二极管阵列的模拟

我们报告了对激光二极管棒 (LDB) 获得的输出功率和二维激光二极管阵列 (LDA) 的功率密度的分析。提出了一种新的 LDA 设计并模拟了它的热状态。由标准连续波 LDB 组成的拟议 LDA 的连续波输出功率（输出功率 100 W，效率 50%，腔长 2 mm）可以达到 5 kW cm ^-2。计算了实现这种功率所需的 LDA 散热器微通道中的冷却剂流动参数。
