What is the best laser? Well, usually putting a laser pointer on a rifle is a bit unnecessary. However, if you really want one, I suggest you use PEQ. These are a little heavier than a single laser, but it is one piece. It is a flashlight, a red laser, and most importantly an infrared laser. There…

Larger better and larger laser pointer
How practical is the laser gun? it depends. Using the currently imaginable technology, anywhere between “very” and “worse than useless” let us start from the very practical. That is a laser pointer mounted on a large object, such as a ship or air defense system, which can provide power and cooling. Laser Weapon System-Wikipedia The US Navy…
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….
The laser weapon system currently in use by the Navy
How does the laser work? How realistic is the laser pointer gun in the science fiction movie? What would a realistic laser gun look like? For example, this is the laser weapon system currently in use by the US Navy: Obviously, it can disable missiles, drones, and boats by overheating electronic equipment. Compared with more classic weapons,…
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….
The huge spaceborne laser pointer weapon is technically difficult
There is no air in space, and SBL does not have the problems of beam refraction, absorption, jitter and thermal blooming in the atmosphere. However, the biggest problem with space laser pointer weapons is sufficient power, and the technical difficulty of deploying massive and bulky spaceborne laser weapons in orbit is too high. , Reliable, controllable, high…
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…
China’s synthetic aperture lidar achieves new progress
There are stories about “clairvoyance” in Chinese mythology, but the eyes of all creatures in nature cannot see the distance of a thousand miles. The development of new technologies, especially the development of synthetic aperture lidar (SAL) technology, may really enable humans to have “clairvoyance” capabilities. It is a high-resolution imaging lidar. Its outstanding feature…
Scientists look for laser pulses carrying this civilization signal around strange stars
According to media reports, scientists discovered a strange light curve on the KIC8462852 star, suggesting that there may be an alien civilization here. A huge structure appeared near the KIC8462852 star. To help rule out this possibility, scientists searched for all the signals around the star, one of which was a very short laser pointer pulse. If…
Mankind’s persistent pursuit of laser precision measurement
With the needs of social development, the requirements for clock laser pointer accuracy are getting higher and higher, so the quartz clock came into being, it is timed by the stable quartz oscillator inside the quartz clock. With the requirements of scientific and technological development and the persistent pursuit of precision measurement by human beings, quartz clocks…
