Laser pointer for cats
Most cats like to play super fast with the green 1000mW laser pointer toy. RJ can hear the jingle of his chain anywhere in the apartment. But this great toy has some precautions; although it may not be what we think. The laser pointer is a demonstration of a laser device that works with the laser device. Children's toy laser gun refers to a product with a 200mw laser pointer. The laser is stimulated by the high power laser pointer beam to reflect the intensity of the laser radiation power. If the laser radiation power is too high, it will cause photochemical damage to the body and thermal damage in the developmental stage, especially for children. When the eyes and skin are exposed to laser radiation, it can be Lead to serious consequences. A yellow laser pointer with a wavelength of 593.5nm appeared on the market. DPSS technology has wavelengths of 1342nm and 1064nm, which are obtained by adding two laser beams through a nonlinear crystal. The process of making a yellow laser pointer is complicated, unstable, and low in efficiency. The temperature output power is 1-10mW. If it is too hot or too cold, a mode jump will occur.

The first problem may be, after all, buy a green laser pointer. We certainly will not let all evil scientists take action, because our carpets and curtains are not our own and will not catch fire. We can hardly feel it on our skin. But will it harm our cat's eyes, or even other people? When I drove out of the road at night, suddenly, bunches of unusually strong green "laser" came, and there was light in front of me that I could not see for a short time. Don't think that these are some scenes in science fiction films. It actually happened on the streets of Nanjing. Recently, a citizen reported to a reporter from the Yangtze Evening News: On the roadside in Jiangning District, there are people selling high-power "laser pointers" here every night. Sellers holding laser pointers to take pictures randomly on the street are like selling "advertisements." Sweeping sidewalks with green lasers will not only cause road safety problems, but even cause personal injury.
