Laser, abbreviated as LASER, or laser, refers to the process and instrument of a narrow frequency optical radiation line that generates a collimated, monochromatic, coherent beam through stimulated radiation amplification and necessary feedback reson ...

Laser has been widely used in our life. Supermarket cashiers use them to scan bar codes on products, and professors use them to get students' attention. Cat owners use the red Dot as a toy for their pets, arguably the most popular use for laser Point ...

The green lightsaber is usually used by Jedi with strong power. Mind movement abilities, such as moving large objects and mental skills, are just some of the useful tools in these Jedi skills. The Jedi Consul is best known for their alignment with th ...

There are three conditions for generating laser light: pump source, gain medium, and laser cavity. The pump source is responsible for providing energy, the gain medium is responsible for providing the conditions for population inversion, and the reso ...

The Laser pointer often encounters problems such as focusing during use. There are three common easy methods to determine the position of the laser high point: printing method: make the cutting head of the laser cutting machine move from top to botto ...

The laser light source is a point light source that emits light from excited particles under the action of radiation. This is a new light source technology. This kind of laser light source has high brightness, long service life, strong directionality ...

Defensive pens are also called tactical defense pens, self-defense pens, and tactical pens. So far, they have not been explicitly stipulated as prohibited or controlled items by any law. Of course it is not illegal to carry it with you! Even if you t ...

Place the laser light in a high-rise or mountain-top scenic area, the beam shoots into the distance, and a bright green light appears in the sky, which is very dazzling. The biggest advantage of laser headlights is the long exposure distance, but it ...

The working medium of the astronomical laser pointer is divided into solid (such as lithium cesium triborate crystal) and gas (such as carbon dioxide). The green light is generally solid-state laser, and the main components are excitation source, con ...

The green laser pointer can emit a bright, highly visible green laser beam and spot, which is the most sensitive Green laser pointer for human eyes. The brightness of the green laser pointer is five times that of the red laser. The 808nm infrared las ...
