Beam Quality And Convergence Ability Green Laser Pointer

The disadvantage of ordinary semiconductor green laser pointer is the poor light condensing ability. This results in high cost, low efficiency, and high power consumption during use. The directivity of the laser is very good. However, the semiconductor laser is emitted like a large bell mouth, and the output light is seriously divergent. Only use the method of adding optical lens group when using. According to Zheng Wanhua, the power of a semiconductor laser is generally around 10 watts. In high-power applications, hundreds or thousands of semiconductor lasers are often required. Even tens of thousands of semiconductor lasers are combined. Assume that a semiconductor laser is added with three optical components. Add 30,000 components before a semiconductor green laser pointer. "
