中文摘要：
半导体激光器在各领域的广泛应用要求其输出功率不断提高，使得多芯片集成封装大功率半导体激光器的发展成为主流之一。针对典型的12只芯片以阶梯形式封装的百瓦级激光器，利用ANSYS软件进行了稳态热分析，模拟得出芯片有源区温度及其热耦合温升与热沉结构尺寸变化的关系曲线，分析了该激光器热特性，进而提出一种使芯片散热较好的热沉结构。
英文摘要：
The semiconductor lasers are widely used in various fields, this requires that their output power is increasingly improved, so the development of high power semiconductor laser with multichip-packaging is one of mainstream. A typical hundred-watt semiconductor laser packaged with 12 chips in ladder form was analyzed in thermal steady-state, obtaining the rule curves of the temperature of active region of chip and temperature rise by thermal coupling in different parameters of heat sink, and a heat sink structure with better heat dissipation was put forward.
