自聚焦光纤对半导体激光束的准直研究

Research on collimation technique of semiconductor laser withautofocus optical fiber

介绍了一种新颖的利用自聚焦光纤对半导体激光束的准直技术。该方法结构简单、调整方便。实验研究表明其可使大发散角的半导体激光束压缩到０．０１°的数量级，适合作半导体激光器的准直元件而运用于精密测试领域。

This paper described the novel collimation technique of semiconductor laser with autofocus optical fiber.The structure is simple and easy to adjust.The experimental research shows that larger divergent angle of semiconductor laser is turned to 0.01° level.So,autofocus optical fiber for collimation of semiconductor laser is suitable to apply in the field of precision measurement.
