What does the laser pointer use to attract customers?

In the past five short years, the laser industry has developed rapidly, from a very niche industry to a hundred billion-level mass industry. All kinds of industrial laser pointer, especially fiber lasers, are applied to all walks of life, involving micro processing such as marking, engraving, and drilling of metal materials, and fine processing such as…

What regulations do green lasers emit?

Today, the maximum power of light emitted by all green lasers has reached the FDA-specified 5 mW. The current green laser pointer manufacturers are listed in alphabetical order in the accompanying photo gallery with a brief overview of their models. Among them, only Viridian manufactures green lasers. The remaining products mainly provide red laser products…

laser sighting devices on defensive pistols

The use of laser sighting devices on defensive pistols or tactical rifles is an effective way to add traditional sights (optical or iron sights). Compared with traditional sights, Laser pointer has many advantages. Laser-equipped guns can be aimed from awkward positions, such as lying on a bed or behind cover. Secondly, unlike iron sights, lasers are easy…

How to judge whether the laser pointer is dangerous

Fortunately, not all laser pointer are dangerous. Unfortunately, it is not always easy to tell which ones are safe. Although the US Food and Drug Administration (US Food and Drug Administration) regulations require that most laser products must bear appropriate warning labels, sometimes this information is missing or insufficient.About 150 mWh, the laser beam can be felt…

Gas laser engraver

In these lasers, the laser medium is composed of one or a mixture of gas or vapor. Gas lasers can be classified according to the type of transition that caused their operation: atomic or molecular. The most common of all gas laser pointer is the He-Ne (He-Ne) laser. The presence of two atomic species (helium and neon)…

Interaction between laser energy and material

The influence of the interaction between laser engraver and material largely depends on the wavelength and power level of the laser, as well as the absorption characteristics and chemical composition of the material. The first generation of laser marking machine is the lamp pump YAG laser marking machine. It is large and has low energy transfer efficiency….

The origin of the gas laser pointer

The HeNe laser was the first continuous wave (cw) laser invented. A few months after Maiman announced the invention of the pulsed ruby laser pointer, Ali Javan and his colleagues W. R. Bennet and D. R. Herriott announced the creation of their continuous helium-neon laser. This gas laser is a four-level laser that uses helium atoms…
