摘要：

为了测量两种有源区材料半导体激光器的温度灵敏度,文中对InGaAsP/GaAs无铝和AlGaInAs/AlGaAs/GaAs有铝的808 nm大功率半导体激光器,采用阈值电流法衡量两种有源区材料激光器的特征温度。在各种温度下实验性地测量激光器的P-I曲线,并采用线性拟合法得到阈值温度线性关系,实验结果表明有铝激光器温度性能明显优于无铝激光器。

关键词: 有铝激光器, 无铝激光器, 特征温度, 阈值电流法

Abstract:

At present,AlGaInAs and InGaAsP have been mainly used in 808 nm high-power laser diode active layer,and the semiconductor laser is very sensitive to temperature.In order to measure the temperature sensitivity of two active layer material LDs,the threshold current method are used for 808 nm high power Al-free InGaAsP/GaAs lasers and Al-containing AlGaInAs/AlGaAs/GaAs lasers to measure the characteristic temperature.We test the P-I curves at various temperatures and obtain the linear relationship between the threshold current and temperature by linear fitting.Experimental results show that the temperature properties of aluminum laser are better than those of the Al-free laser.

Key words: Al containing LD;Al free LD;characteristic temperature;threshold current method
