The color of the Aurora green laser pointer is great!
Class IIb lasers in this class may cause damage if the beam enters the eye directly. This usually applies to lasers with a power of 5-500 mW. Such high-powered lasers can also be a fire hazard and can slightly burn the skin. It's like a burning laser pointer. For astronomy enthusiasts, a 20mW to 50mW power point pen can meet the requirements of pointing stars. Power above 50mW can be particularly harsh in dark indoor conditions. The price of laser pen is mainly related to its bandwidth and stability, the narrower the bandwidth, the more expensive the price, but the human eye simply can not distinguish this bandwidth gap, so the power of 50mW below, the price of 100 yuan laser pen is more appropriate. In addition, laser pen power consumption is generally larger, in line with the principle of environmental protection and savings, with a good rechargeable battery is also very necessary.

To turn on the laser, the researchers input an yi or electric current into the outer ring of the grid, converting the energy into the soft energy of the laser. The loops are connected by racecourse loops, precisely placed to guide the gentle particles along an approach path. Boubacar Kante, an electrical and computing device engineer at the University of California, San Diego, says that while the outer ring transmits the laser most efficiently, a complete ring grid is needed to help guide the photons. The use of laser Pointers has become widespread. Laser Pointers are useful tools for educators in classrooms, conventions and conferences. However, due to the low cost and ubiquity of supply, these high powered laser Pointers are now being bought and used by the general public, including children, in ways their manufacturers don't want. As a result, serious concerns about the dangers of laser Pointers have surfaced.
