求翻译：半导体激光和固态红宝石激光及氦氖气体激光很相似，它们都能发出方向性很强的单色光束.不同之处在于半导体激光较其他激光体积小（长度约只有0.1MM），而且在高频时易于调制，只需要调节偏压电流即可.由于具有这些特性，所以半导体激光是光钎通信中最重要的光源之一，它可以运用于录像机，光学阅读机及高速激光打印机等，除此之外，它还广泛应用于许多基础研究与技术方面，如高分辨率气体光谱学及大气污染检测等.是什么意思？

Very similar to the semiconductor laser and solid-state ruby ​​laser and helium-neon gas laser, they can issue a strong monochromatic beam direction. Difference lies in the semiconductor laser is small compared to other laser volume (length of about 0.1mm), but also in the high-frequency easy modula

Semiconductor laser and solid ruby laser and helium neon gas laser is very similar to both of them can have a strong direction from the monochrome beam. What is different than other laser semiconductor laser is small (only about 0.1 length MM), and in the high frequency modulation, and only when you

The semiconductor laser and the solid state ruby laser and the helium neon body laser is very similar, they all can send out the directive very strong monochromatic light beam. The similarity lies in the semiconductor laser to compare other laser volume slightly (length approximately only then 0.1MM

And solid state Ruby Laser and Semiconductor Laser he-ne gas laser is similar to They are can issued directional is strong of monochromatic light beam. different of Department is Semiconductor Laser more other laser volume small (length about only 0.1MM), and in high frequency Shi easy to modulation
