I don’t know why, but I can provide details about what I have observed with my cat-a cat that “asks” me every night in circles around the house. My total experience includes about 10 cats/kittens and 3 color high power laser pointer. Unfortunately, only one color laser was used for each cat, and only one cat…

Why do cats like to chase red laser pointer lights?
Is the development of a cat playing with a high power laser pointer different from that of a cat playing with a physical toy? I grew up in the religion of the big red dot. It was taught to us when we were very young, although I hope it is based on almost the same principles that…
What is the laser pointer used for?
Before the advent of Powerpoint and even the PC, in the era of plastic “foil” called Vugrafs, when the speaker narrated it, the high power laser pointer was used to direct the audience’s attention to the various parts of the “slide”. Since then, we have started to animate and have a pointer that can be controlled with…
Does playing with the laser pointer hurt the cat’s psychology?
I imagine it is frustrating for the cat to finally find a high power laser pointer. Toys such as these are designed to exercise prey drive. Prey drive is the most powerful instinct possessed by cats. Once they are capable, they will instinctively track, chase and catch (or swoop). Kittens honed this skill on their litter…
Does the laser pointer make people blind?
When the laser hits your eye, you will automatically turn it off to protect it. Below about 50mW of high power laser pointer power, this reflection speed is fast enough that the energy absorbed by the eye will not cause permanent damage. The premise is that the light is visible. Infrared lasers will not trigger this reflection,…
The laser pointer beam does travel a long distance
How far are we from the handheld laser gun? Will it replace traditional ammunition? Changing the high power laser pointer weapon carried by a typical rifle man is incredibly far from our current level of technology and any reasonably foreseeable past. We are not talking about just needing better batteries and better laser transmitters, but about the…
Is there a difference between a rifle and a laser pointer assault rifle?
Is there a laser pointer with a clearly visible high power laser pointer that will not cause damage or risk aircraft interference? I usually show a picture of the Spark Optical Range for this, but this time I will show one in China. This photo shows the first successful measurement of the moon’s distance from China using…
What if someone looks at the laser pointer from the rifle scope?
The scope is enlarged. Lasers are already very dangerous. Even a cheap high power laser pointer, when pointed at your eyes, can ruin your vision. I suspect that the scope will magnify the laser, and depending on the type of laser, it will bring you a greater risk of damaging your eyesight. How effective is the…
Are there laser pointers that are not considered ultraviolet or infrared?
A very dim visible laser can solve this problem. For example, under most conditions, a few microwatts in the visible high power laser pointer beam are almost invisible. However, if you are looking at a light beam scattered in the atmosphere rather than a light beam directly reflected from the surface, it may be difficult to see…
Very compact thermal rifle sight laser pointer
If two countries have soldiers at war and both have infrared high power laser pointer night vision goggles, can’t they see each other’s location? Yes, this is a good question. Since I retired in 2003, because these things are common, my information is a bit limited. In Korea in the mid-1980s, we had passive night vision, called…
