What is the burning power of 1 mile laser pointer?

200MW is the starting point. In actual daytime use, the higher the milliwatt power, the better the visibility. A minimum of 200MW is a good starting point for shooting in tree artists and shooting ranges. However, the stronger it is used during the day, the better. Focusing - it is also a wise choice to use a laser that can widen or narrow the beam. You can increase the intensity of the beam by thinning or focusing it. This will make it more obvious during the day. In recent history, technology is developing at an alarming rate. From the progress of computer and Internet era to aerospace and space exploration technology, and then to the breakthrough of life-saving medicine. It is not only applicable to products that we can use as daily citizens of the earth. For example, take a green laser pointer. When the cheap red Keychain laser that is not bright and has no real visible range becomes the norm, anyone can now use high-power laser technology in a convenient and portable handheld form. The wavelength of the light produced by the laser determines the visible color seen by the naked eye. But which color is the best? Which color is the brightest? In general, it is important to note that at the same output power, the 532nm green laser is 7 to 10 times brighter than any other beam color. This means that a 200MW green laser is about 7 times brighter than 200MW of any other color.
