【摘要】 利用等效热注入假设推导出列阵半导体激光器热沉中湿度分布解析表达式,该式包括了影响列阵激光器温度分布的多种因素,如各激射区的宽度,腔长,条间距以及管芯在热沉上的位置,它比以往结果更符合实际情况.通过计算对影响列阵激光器的散热因素,从热特性角度改善其锁相特性,以及热散射角的大小等问题进行了讨论.更多还原

【Abstract】 The concept of the effective width of a heat flux penetrating into a heat sink is used todevelop a formula to describe the temperature distribution in laser arrays.The formula in-cludes various influencing factors such as active region width, cavity length, stripe space andthe location of a diode chip on the heat sink.The formula is more practical compared withthe previous ones.A discussion is given to the heat dissipation, phase-locking improvment andheat divergence.更多还原
