Fiber laser is known as the most advanced third-generation industrial processing laser pointer, and it is also a high-end laser pointer developed by countries all over the world. It is considered a new laser technology, showing the competitiveness of fiber lasers. In the future, fiber lasers will still be the mainstay of the laser industry,…

Will the ground forces have laser pointer rifles?
If so, what are the limitations compared to traditional rifles? Maybe one day, but battery technology is far behind the technology needed to make high power laser pointer rifles practical. Another problem is that if the laser is emitted when it is raining, snowing, or when there are many particles in the air in general, its effectiveness…
Can drones be blinded by laser pointers?
It depends on which “drone” you are referring to. If you mean high power laser pointer quadcopter, because the media has adopted the broad term “drone” and narrowed it down to just this one device (which I think is a bit unfair), then no. In fact, most radio-controlled airplanes are quadcopters that are remotely piloted by humans….
Why is the laser pointer red?
The question should be “Why are cheap high power laser pointer red?” Because you can get more colors than red. The reason is that infrared and red LEDs are the easiest to manufacture, while solid-state lasers are just very complex LEDs. The first LED is IR, then red, then orange, and so on. Each new color requires…
Is it illegal to shine a laser pointer on someone else’s window?
Even if you didn’t hurt anyone or hit anyone in the face with a high power laser pointer, if you call the police, you are likely to be summoned for misconduct. This is a reasonable charge, because at least you are disrupting and may scare people in their home. In the past 5 years, laser modules…
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…
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…
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…
Coherence keeps the laser pointer beam focused at a distance
Why is the laser beam so thin? There is no absolute reason to say that they must be thin. The “green laser pointer” is only light amplified by stimulated radiation, so if you prepare some optical gain medium in its excited state and put in some “seed” light of the correct frequency, it will be…
A more powerful laser will produce a brighter scattered beam
If you see a point or a beam, you have a visible laser. Whether you see a light beam in the air depends on several factors: In clear air, the light beam will be scattered by air molecules in a process called Rayleigh scattering. The process is fairly weak and depends on atmospheric pressure, green laser…
