The pick is one of the vulnerable parts in coal mining and roadway driving machinery. It is the main tool for coal falling and crushing. Its performance directly affects the production capacity, power consumption, working stability and other related parts of the shearer There are many kinds of picks for the long service laser pointer life. The…

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…
The green laser is brighter than any other laser color
Generally, under the same power, the 532nm green Laser pointer is 5-7 times brighter than any other laser color. Whether it is light colors such as blue, red, purple/purple or yellow, green is the most visible material. For example, a 100mW green laser is actually 5-7 times brighter than a 100mW red or violet laser pointer. Therefore,…
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…
The time when the green aiming laser was first manufactured
Safety professionals pay special attention to secondary impacts, which are experienced during key activities such as driving on busy highways. If the driver loses control due to instant visual effects or psychological effects (fright or panic), the consequences may be very bad. It is reported that after a similar incident with a more powerful light…
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…
