Details of the high power of the laser pointer
If you move it, you can light a match or shoot something through. The other is at 100MW, 200MW, 300MW. You can check the following website. On their website, there is a video that is 100MW, and you can light a match. Yes, there are 5MW, 10MW, 20MW, 50MW, 100MW, 200MW, 300MW for thin light. In fact, there are still 500MW, but no one dares to sell it, because it is dangerous to people. It is impossible to shoot through things under 100 in a short time.

800 to 1,000 yuan, it is possible to make a green laser with 1W power, and tens of thousands of milliwatts are all virtual standards. The efficiency of the laser is not very high. Taking green as an example, the output power is about one-eighth of the power consumption. One tenth. If it is a green Laser pointer with a false power of 5000mw for thirty to fifty yuan, the general actual power is about 30-50mw, and the visual range is about kilometers, which will be farther. If it is a real power of 5000mw laser, It is called a laser flashlight, taking Nuoqing NQ-410 as an example, the measured 4000-4500mw, blue laser flashlight, although the power is large, but the laser divergence angle is large (do not understand the divergence angle, you can download it in Baidu), and the range does not have low-power green The light is far, of course the brightness is much brighter than the general low power.
