| 摘 要： | 以2W连续红外(980nm)半导体激光器(InGaAs)和120mW连续红外(980nm,带制冷器与尾纤)半导体激光器(InGaAsP)为例,测量激光器输出光束的波长随工作电流变化的规律。实验结果表明:工作电流增加,光束波长向长波红移,斜率分别近似为0.374nm/100mA、0.220nm/10mA;工作电流大时的红移现象比电流小时明显。

| Abstract: | Two kinds of semiconductor lasers (InGaAs, 2 W, continuous output, infrared 980 nm and InGaAsP, 120 mW, continuous output, infrared 980nm, including tail\|fiber and cooler) are taken for examples and the rules of the change of semiconductor lasers output wavelength correspondig to operation current are experimentally investigated. The results show that the emission wavelength of the laser shifts in the direction of long wavelength as the operation current rises. The slopes are approximately 0.374 nm/100 mA and 0.220 nm/10 mA, respectively. Furthermore, the change of wavelength becomes more obvious while laser works in large current. |
