This is not only because the 532nm laser green beam frequency is the brightest color in the visible spectrum, but also because the green laser is easily modified during the production phase to achieve higher laser output. The potential of handheld lasers on the market today ranges from simple 5mW green laser pointers to 100mW or even over 300mW. If you know where to look, some of the world's most powerful laser pointers actually only need one or two, but remember, use your high-power lasers with caution. If the beam can burn industrial-strength electronic tape, can we see the potential hazards of human flesh or eye retina? Don't let the attraction of high-power lasers distract you from the dangers you have, be careful, and don't let the technology enjoy you.
