摘要	PURPOSE:To facilitate coupling with other optical systems by a method wherein the center of the emission window for a main laser beam and for a monitor beam is in line with the optical axis vertical to a bottom and a hollow screw and the bottom of a cap are concentrically formed. CONSTITUTION:A bottom 1 and cap 9 are hermetically sealed at flanges 19, 19' in dried N2. A main laser beam 14 is focused, for coupling with an optical fiber, by a lens positioned just outside a window panel 1 A monitor beam 15 is thrown outward through a window panel 8 and then through the cavity 3 of a screw 4. Accordingly, a photodiode located at an end of the screw 4 senses and determines the relative optical energy of the monitor beam 14. By attaching a coupling lens at the center of a main beam transmitting window 111 or hermetically attaching a lens to an opening 10 instead of the window panel 11, a laser diode is obtained that may effectively be coupled to an optical fiber without an external lens.
其他摘要	用途：通过一种方法与其他光学系统耦合，其中主激光束和监视光束的发射窗口的中心与垂直于底部的光轴和空心螺钉以及盖子的底部对齐是同心形成的。组成：底部1和帽9密封在干燥N2中的法兰19,19'。主激光束14通过位于窗板11外部的透镜聚焦，用于与光纤耦合。监视光束15通过窗板8向外抛出，然后穿过螺钉4的空腔3。位于螺钉4一端的光电二极管检测并确定监视光束14的相对光能。通过将耦合透镜安装在主光束透射窗口111的中心或将透镜密封地连接到开口10而不是在窗口面板11上，获得激光二极管，其可以在没有外部透镜的情况下有效地耦合到光纤。
