Lasers can be very powerful. Conditions in the Sun's core can be reproduced in a laboratory on Earth thanks to some of the most powerful lasers in the world. Lasers can heat materials to extremely high temperatures—more than a million degrees. Lasers range in size from smaller than the diameter of a human hair to larger than a football field. The stored energy for amplification can come from solids, liquids, gases, or even electron beams. Many modern green laser pointer are largely tunable. At these temperatures, atoms cease to exist, and electrons are stripped of the core they respect, leaving a soup of ions and electrons.
The next thing to note about laser pointers is the warning sign on their side. You may see a "Danger" sign or a bright yellow triangle with a laser beam inside or a "Caution" sign - this means you should not look at the laser pointer as it could hurt your eyes. Laser scientists classify hazardous lasers by marking them with categories. Lasers that are completely safe and will not cause any damage to your eyes are Class 1 lasers. The green laser pointer is the most popular 10000MW laser pointer in the world, because the green light beam is obviously 6 times more than the red light beam, and the price is much cheaper than the blue and yellow. Users generally use a green laser pointer. The emitted light wavelength is 532nm green high power laser pointer, the laser type is class IIIA, and it uses two AAA batteries.
Now imagine the damage this could do to your skin or worse, your eyes. It's pretty scary to think that anyone can buy these lasers online. My supervisor bought the laser pointer online and it is said to be less powerful than it actually is. He did some power tests on them and found them to be class 3 lasers! They can burn through paper and pop balloons, so be careful when buying laser pointers online.
