本期【Rayclass | 锐课堂】我们来说说一座待发掘的宝藏——光纤输出半导体激光器。

 

什么是光纤输出半导体激光器?

 

光纤输出半导体激光器是通过特殊的光学系统对半导体激光器出射的激光进行光束质量的改善,并在满足光纤耦合的条件后,通过聚焦把激光耦合进光纤进行传输的半导体激光器模块。

Fiber Delivered Direct Diode Laser is a semiconductor laser module that uses a special optical system to improve the beam quality of the laser light emitted by the semiconductor laser. After meeting the fiber coupling conditions, the laser is coupled to the fiber for transmission by focusing.

 

与其他激光器(气体、固体、光纤激光器)相比,光纤输出半导体激光器有着许多不可比拟的优势:

Compared with other lasers, Fiber Delivered Direct Diode Lasers have many incomparable advantages, for example:

 

(1) 电—光转换效率高(超过50%);

(2) 工作寿命长(超过10万小时);

(3) 能够直接电调制;

光纤输出半导体激光器有哪些应用?

 

激光锡焊

Laser Soldering

以激光热源为主体,对锡料填充熔融固化达到连接、导通、加固的工艺效果。优点:非接触,无静电,无空间限制,耗材少,速度快。

The laser heat source is used as the main body to fill and melt the tin material to achieve the process effect of connection, conduction and reinforcement.

Advantages: non-contact, no static electricity, no space limitation, less consumables and fast speed.

 

激光透射焊接塑料

Laser Transmission Welding of Plastics

应用中,需要其中一种材料能够透过激光,而另一种材料要吸收激光或者材料表面涂层吸收激光,两种材料需要连接的部分在压力作用下,随着激光束移动形成材料间的连接带。优点:牢固,密封,易控制,可异种材料焊接。

In applications, one of the materials needs to be able to transmit the laser, and the other material must absorb the laser or the surface coating of the material must absorb the laser. The part of the two materials that needs to be connected under pressure acts as the laser beam moves to form a connecting band between the materials.

Advantages: firm, sealed, easy to control, welding of dissimilar materials.
