| 摘 要： | 通过光热反射技术测量大功率二极管激光器腔面温度,并取得了初步结果。由于是非接触探测,故而比较真实反映了正在工作的大功率二极管激光器腔面温度。通过实验及分析表明,有源区是产生热最多的地方,通过测量不同偏置电流时的光反射信号幅值,获得了腔面温度分布图。整个实验装置及测量方法简单可靠,可望实际用于大功率二极管激光器的腔面温度评价及性能优化研究。

| Abstract: | The cavity facet temperature of high power laser diode can be measured by opto-thermal reflection technology. The cavity facet temperature of high power laser diode can be obtained by this non-touch detection method. It has been revealed that there is a large amount of heat generation in the active region while the device lasing through our experiment and analysis,the cavity facet temperature profile can be achieved by measuring optical reflecting properties at different facet position. This measure system ... |
