How does the high-power laser pointer solve the heat dissipation problem?
The device uses picosecond pulses from a green laser pointer to scan the cellulose in the paper but evaporate the toner. The main goal of canceling printing is to reduce the carbon footprint of the paper and printing industries. The paper industry is very chaotic, producing millions of tons of carbon dioxide every year. Recycling paper is definitely a step in the right direction, but it is still a very resource-intensive process. The green laser pointer are supervised and tested to ensure they stay below 1 milliwatt, and most of the devices you can buy from direct dealers who sell them with the best knowledge are incorrectly marked as safe, but they do exist risk. These laser pointers are usually battery-powered and are more dangerous at blue or green wavelengths. Laser pointers seem to be a big problem for local law enforcement and the FBI. No, not your high school physics teacher. He realized that there was always a red LED on her forehead, and some clever people asked the class if they wanted to "learn laser". It's not that your cat can never dance wildly on kitchen tiles.

In addition, do not try to aim the visible green laser at the eyes of moving vehicles, airplanes, people and animals in the distance. Anyone who uses this type of equipment should wear laser goggles to protect against high-power laser radiation. The powerful 1000mW green laser pointer is not a toy, but a powerful weapon in the hand. If you have a very powerful laser pointer, you should use the device very responsibly. Therefore, you should absolutely avoid direct exposure to other people's eyes (whether they are children or adults). Otherwise, the retina may suffer great damage (it cannot be repaired according to the intensity of the laser), and it is easy to avoid this damage through proper treatment. First of all, the technical content of the green high powered laser pointer is not very high. It is mainly composed of several main components: battery box, circuit board, 808nm infrared laser diode (pump source), laser crystal (Nd: YVO4 crystal, KTP crystal), among which The collimating lens group has been enlarged.
