Recently, in terms of laser popularity, the green laser has always won the championship, and red is the only beam color available. There are many different laser pointer colors, such as blue, yellow, purple and infrared, but it is green at a frequency of 532nm and has become the most popular color. This is mainly because at the same output power, each green laser will produce a visually spectacular laser pointer, which looks brighter than any other color beam, so it does look the brightest, so it is the most commonly used beam .
