Why do most people who don’t like tattoos refuse green laser pointer removal and choose to cover it up?There may be several reasons for this. 1. Laser removal is expensive and requires multiple treatments to reduce the appearance of the tattoo. In fact, it is much more painful than the actual tattoo. 2. It is usually easy…

Is the green laser more dangerous than the red laser?
Why does my green laser pointer (532 nm) turn yellow when it touches the orange part? It will not change the color on any other surface. Due to the fluorescence of the surface material/pigment/paint. Usually we can observe it with ultraviolet light or at least a blue light source. But F. means consuming certain wavelengths of light…
The laser pointer beam is located inside the fiber
Can you pass a safety laser with a mirror? You mean like in the movie? Who designed such security? That is a defeated system. Let me give an example of a safety laser. The optical fiber is buried in the gravel “moat” surrounding the facility. Fences are usually used with optical fibers. The laser pointer beam is…
There is no visible laser pointer in imminent danger
If I get lost in the wild, but I have a laser pointer, can I point it at the airplane to draw attention for help? It is illegal to point the laser pointer at the aircraft at will. Now I have added that dazzlingly obvious statement to my answer in the editor. With a little digging,…
Laser pointers in Star Wars look like bolts
Why do the lasers in “Star Wars” look like bolts when they are actually beams?Because without these special effects, the movie is really boring. Just imagine if it was in the real world. Hans pulled the trigger, and at the same time we saw a cloud of smoke, there may be some sparks hitting it….
Do I really need a laser pointer or light on my gun?
How accurate is the laser rangefinder? The unit’s documentation will tell you that its capabilities vary from model to model. The important thing is to learn to use the system and practice within a known distance until you learn how to aim the unit. Aiming and getting the beam you want is an acquired skill….
The laser pointer sensor is really safe
Not only can “power” users be used, can any other species invent a laser pointer or dagger that can retract the laser blade? Well, there is a laser type weapon called the energy sword. It is made of plasma-almost their version of lightsaber (saber is just a sword). Variants include blood blade, plundered silver, and green variants….
STMicroelectronics launches laser ranging sensor
Across multiple electronic applications, STMicroelectronics, the world’s leading semiconductor supplier, released the second generation of laser pointer ranging sensors. The new sensor VL53L0 is based on the successful FlightSense MT technology to achieve faster, farther, and more accurate ranging functions, greatly improving the camera performance of mobile phones and tablets, for robots, user detection, drones, Internet of…
Laser weapons change air combat each shot costs $1 and can be fired continuously
It is said that the theoretical basis of laser was established by Einstein in 1917, but it was not until 1957 that people really discovered laser pointer. Laser has the characteristics of good directionality, concentrated beam, good monochromaticity, and powerful power. It does not require much imagination to see the potential of laser as a weapon….
Physicists photographed crystal structure transformation under laser beam
Laser beams can be used to change the properties of materials in extremely precise ways. This principle has been widely used in technologies such as rewritable DVDs. However, the basic process is generally carried out at such an unimaginable speed and such a small scale that it has not been directly observed so far. Researchers…
