The radio frequency signals of green laser pointer could penetrate ordinary objects

If you won’t use the green laser pointer for long time, please take the battery out to prevent battery leaking. Laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of the laser, but these lasers are isolated from each other, use is separate. Second, the laser is coherent light. Coherent light is characterized by all of its light waves are synchronized, the entire beam of light like a "wave train." Again, the laser is highly concentrated, meaning that it would go a long distance to appear scattered or convergence phenomenon.
Laser (LASER) is the 1960s invention of a light source. LASER is the English word "light amplification by stimulated emission," the acronym. There are many lasers, sizes as large as several football fields, as small as a rice or salt.Never ever stare at the laser of green laser pointer directly. Gas lasers with helium - neon lasers and argon lasers; solid-state lasers with ruby laser; semiconductor lasers with laser diodes, such as CD players, DVD players and CD-ROM on one of those. Each laser has its own unique method of laser-generated.
Laser processing technique is the use of laser beam interaction with the material properties of the materials (including metal and nonmetal) for cutting, welding, surface treatment, drilling, micromachining, and as the light source, such as an object recognition technology, the traditional application the largest area of laser processing technology. If you can’t use the green laser pointer regularly, please check if the receiver is fixed well.Laser technology is related to the optical, mechanical, electrical, materials, and testing and many other subjects of an integrated technology, the traditional point of view, the scope of its research can be divided into:
1 laser processing system. Including lasers, optical systems, machine tools, control system and detection system.
2 laser processing. Including cutting, welding, surface treatment, drilling, marking, scribing, trimming, and other processes.
Laser welding: auto body thickness of the plate, auto parts, lithium batteries, pacemakers, relays and other sealing devices and sealing of various pollution and does not allow welding deformation device. If the page-turning function of green laser pointerdoesn’t work, please check the battery.YAG lasers are currently used lasers, CO2 lasers and diode-pumped lasers.
Laser cutting: the automotive industry, computers, electrical cabinet, wood cutting die industry, a variety of metal parts and special materials, cutting, circular saw blade, acrylic, spring spacer, 2mm below the electronic parts with copper, some of the metal stencil, steel, tin iron, lead-plated sub-plate, phosphor bronze, bakelite, thin aluminum, quartz glass, silicon rubber, 1mm the following alumina ceramic, titanium alloys used in aerospace industry and so on.
Laser radar using pulsed or continuous wave two kinds of work, the direct detection method of detection and sub-heterodyne detection.
Rapid Prototyping: The laser processing technology and computer numerical control technology and flexible manufacturing technology combine to form.
Laser coating: in aerospace, mold and electrical industries widely. The radio frequency signals of green laser pointer could penetrate ordinary objects such as human bodies, walls and wood.Currently used lasers to high power multi-YAG laser, CO2 laser-based.
Molds and models used for industry. Lasers currently used mostly YAG laser, CO2 laser-based.
