Burning 5mw laser pointer to light a match
Therefore, this pen type green laser pointer low consumption series is mainly used for business meetings, conferences, lectures, laboratory experiments, museums, galleries, exhibitions, etc. Also, it is the most important and common astrology application. Observe with a telescope. The brightness of a laser is determined by its power. The higher the power, the brighter the laser. Although this only works for fixed wavelengths (colors). If you've worked in the laser market, you're probably familiar with the fact that lasers above a certain intensity have a certain ability to burn. Burning lasers can light matches, pop balloons, cut electrical tape, and etch certain types of wood, fuses, and more. Fortunately, not all high power laser pointer are dangerous. Unfortunately, deciding which is safe is not always easy. FDA regulations require that most laser products carry appropriate warning labels, but this information may be missing or insufficient. According to the American Academy of Ophthalmology, outputting more than 5 milliwatts of laser light can cause immediate and severe retinal or skin damage.

Obviously, this is very different from a laser. Analog white light (a superposition of red, green, and blue light that our eyes perceive as white) cannot be used without three or more laser pointers. Lasers are coherent, even if you combine red, green and blue lasers (already done) and ignore the monochromatic requirement of the laser pointer crow. This means that all waves from a true laser are homeomorphically polarized. It is impossible to do this entirely with three different lasers at different wavelengths. For example, green and red lasers with the same output power will not have the same brightness.
Therefore, at the same output, the green laser pointer will be 5-7 times brighter than other laser colors. If you play with the cat laser pointer toy, give the cat a tangible object to catch, feed, or treat at the end of the game. In other words, I caught it. If they can't catch the "dots" and put them away at your convenience, there are "inappropriate victims" offline: other cats in the house, or ankles. Therefore, a 200 MW green 532 nm laser pointer crow is 7 times brighter than a 200 MW 405 nm violet laser and 5 times brighter than a red or blue laser.
