Is cat playing with laser pointer risky?
The absorption capacity of different colored objects to different wavelengths of laser light varies greatly. Homochromatic absorption is the worst, associated with white. However, the absorption of colored objects is most obvious. For example, the green laser pointer recommendation is easy to illuminate the game, but illuminating greenhead games is more annoying. If you are a super laser enthusiast or have research needs or other special purposes, want to buy a high power blue laser pointer that does not meet the low power green red laser pointer. The problem is that there is no uniform price on the market for high-power blue laser Pointers. And many companies fool consumers by mistaking low-power Blu-ray for high-power.

Since the advent of the first laser pointer, a large number of laser crystals have been dumped on the market around the world. The range of laser Pointers has become the most popular laser among laser enthusiasts and enthusiasts. Green laser Pointers are widely used in military, astronomy, scientific research, education, business meetings and other high-tech fields, but they play an essential role in the joy of life. I like to try the green laser pointer, which is a very powerful entertainment tool. Leds are diodes. An LED is just a semiconductor diode (PN) junction that can emit light over a wide spectral range. The light is different. There are different types of leds that can produce different colors (or wavelengths). Speaking of lasers, lasers are the name of the technology used to produce coherent beams of light by stimulated emission. If there are gas lasers, semiconductor lasers, solid-state lasers, etc., there are many kinds of lasers.
