During this period, I studied the laser pen, what kind of structure was studied, and the danger of the law. Now I can also make my own laser pointer. I produced a powerful laser pointer of 2000mw or 3000mw. I didn't know how to do it before I did it, so I bought it at a store. However, the laser at the store was so bad that it broke when it bought.
