Best laser pointer for cats does not hurt cats
The wavelength and power of the laser product determine the degree of damage of the laser to various tissues of the human body. The wavelength determines the absorption characteristics and damage mechanism of the laser. The power is related to the degree of laser damage. They look like business cards for laser products, which represent how harmful it is and users should pay attention to them. Next-generation laser pointers use diode lasers as light sources. The diode green laser pointer initially produces a beam of 690 nm. The difference between 633 and 690nm may seem small because both are visible red wavelengths, but according to the interpretation of the human eye, the difference is large. The 633 nm seen by the human eye is five times brighter than 690 nm. This explains why the early diode laser pointer needed 5mW of power to match the brightness of the 1mW pointer at 633nm.

These early high powered laser pointers were intended for use in astronomy at night. The difference between red and green lasers is that you can see the beam at night. They are not available to everyone, and the price is quite high. Although we have supervised and tested laser pointers to ensure that they stay below 1mW, most of the devices you can buy from direct dealers are mistaken for safe and they sell them to the best of their knowledge. But they are risky. Moreover, if you look at samples of injured children, you will find that the average green laser power they are exposed to is at least 45mW. It is indeed wrong to let someone who does not have proper laser safety training handle this matter. For the products I have seen and purchased, all these lasers can be purchased at specifications below 1mW. In 1997, the FDA issued a warning about the abuse of laser pointers. In some states, such as California, it is illegal to point a laser pointer at someone who realizes that they are in danger, while aiming at an airplane is a crime. Some local governments have passed regulations requiring people who purchase laser pointers to be over 18 years old. It is expected that the upcoming revision of ANSI Z136.1 will include a section specifically dealing with laser pointers.
