CCD camera/Coherent Beam Master

The coupling efficiency is from 50% to 80% in accordance with different types of laser diodes.

“激光二极管->光纤”模块现在可是个热门货。不过进单模光纤的还真是少见。效率不错啊。寿命测试怎么样啊？

功率如何？最大能有多大？

我们现在做的比较多的有两种：
658nm 单模光纤输出70mW左右
639nm单模光纤输出12mW左右

The vendor is Fibertech from Germany, we also are the distributor for their fiber products in China.

This type of single mode fiber is with 3.7um corediameter and 0.12NA, thanks for your attention.
