Play with cats with a fun green laser pointer
What are the characteristics of the 5mW green laser pointer? It uses a pen style design, allowing you to take your cat or dog anywhere. This portable laser can be put in your pocket. You may experience some inconvenience when wearing it outdoors. The red light beams are particularly dazzling and make people's eyes bright. In the Class IIIa laser queue, laser safety remains a major issue. Even if the low-power laser pointer is almost undamaged, it will never be beneficial to point the laser directly at the pet cat or dog. Never try to view the pen with a moving vehicle, airplane, or maintenance panel (such as a mirror). The reflected beam is very dangerous and may cause accidents.

The best way to determine is to use a high powered laser power meter to measure the output. 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 what I have seen and purchased, all these lasers can be purchased at specifications below 1mW. The excitation medium is a gas laser. The helium-neon mixture used in the first continuous laser (Ali Javan, 1961) still has important uses. The output power is low (a few milliwatts), but there is also frequency dispersion. This very pure light is very useful in equipment used for interferometry, holography or alignment (such as public works). Carbon dioxide lasers can achieve high output of several kilowatts and are used for machining and surgery.
