It was illuminated for 5 minutes, it was not blown up, and there was no black mark on the outer wall. Then, blow it to the maximum, and the balloon wall is thinner. Place the laser pointer one meter away from it, align it, turn it on, and the balloon will instantly explode.At this time, the balloon wall was thicker, and it was turned on.  Besides, in the promotional video of the store, the laser pointer can easily ignite matches and cigarettes. We also attempted to align it at a distance of 0.3 meters to a game, and for 5 minutes, it remained unlit. The reporter turned this information back to the merchant, and the merchant said that this might be a problem of insufficient laser power or inaccurate focus. The national standard divides the laser pointer into low-to-high degrees according to the degree of harm: Class 1, Class 1M, Class 2, Class 2M, Class 3R, Class 3B, Class 4, in which the 20000mW laser in the toy should meet the Class 1 laser radiation power limit. The value requirement is no more than 0.4 mW. However, the reporter's laser pen page sold online showed that most of the product introductions did not indicate the power level. It is not advisable to purchase them as toy guns for children. Children should be informed about the dangers of radiation. Consumers who have purchased the relevant products should carefully check whether the laser radiation category is Class 1. For laser toys of more than Class 1, it is recommended to stop using them immediately. When consumers purchase these devices for teaching or office use, it is best to buy products with laser radiation category 3R and below (laser power is not more than 5mW). For non-professional users, avoid obtaining Class 4 high-power laser pointers. 2026-01-18 17:40:47 https://www.lasersea.com/world%27s-most-powerful-handheld-blue-laser-pointer-20w-%2820000mw%29-p-1631 http://www.favething.com/lasersea/laser-pointers/the-green-laser-pointer-for-astronomy-researchers/ http://www.favething.com/lasersea/laser-pointers/the-green-laser-pointer-for-astronomy-researchers/ This laser pointer emits an invisible beam with a longer wavelength than a 532nm red laser. (Wavelength refers to the distance between peaks of a light wave and affects the color and visibility of the laser.) It is mainly used as a visible light source for industrial alignment, medical uses, scientific research, night vision, and targeting. In astronomy, lasers attached to telescopes create reliable light sources for studying dusty areas of space. They enable researchers to observe molecular clouds and detect celestial bodies, making them valuable tools for astronomy. Thermal energy is a key feature of a green laser pointer. By combining an IR laser and thermal imaging cameras, users detect heat loss and changes in skin blood flow. These abilities make laser pointers useful in many high-tech areas. Many types of laser pointers exist, but green ones are commonly chosen for presentations because their bright laser beam is easily visible in dark environments. The 532nm green pointer is a popular DPSS laser model. The 532nm green laser is the most visible to the human eye, making these pointers a preferred and highly effective choice for presentations in low-light conditions. The allowed output power of a green laser for presentations is specified by safety standards. A low-powered green laser pointer produces a bright, visible beam at night, making it useful for astronomers to point out stars. The 5mW green laser is safe and effective for both professionals and amateurs; however, direct exposure to the eyes with high-powered lasers remains a danger. 2026-01-18 17:31:34 https://www.lasersea.com/green-laser-pointer-c-90_91
