半导体二极管激光器（LD)是实用中最重要的一类激光器。它体积小、寿命长，并可采用简单的注入电流的方式来泵浦。其工作电压和电流与集成电路兼容，因而可与之单片集成。并且还可以用高达GHz的频率直接进行电流调制以获得高速调制的激光输出。由于这些优点，半导体二极管激光器在激光通信、光存储、光陀螺、激光打印、测距以及雷达等方面以及获得了广泛的应用。
再翻译一下：关键字：半导体激光器、阈值电流、伏安特性、激光光谱、光谱仪

The semiconductor diode laser (LD) is a practical most important kind of laser. Its volume is small, the life is long, and may use the simple injection current the way to come the pump. Its working voltage and the electric current and the integrated circuit are compatible, thus may with it monolithic integration. And may also use to reach as high as GHz the frequency to carry on the electric current modulation to obtain the high speed modulation directly the laser output. As a result of these merits, the semiconductor diode laser in the laser communication, the light saved, aspects and so on light top, laser printing, range finder as well as radar as well as has obtained the widespread application.

Key words: Semiconductor laser, threshold current, voltage-current characteristic, laser spectrum, spectroscope
