What can lasers be used for? What benefits to people

The application of laser is very wide, including many aspects:

1. Laser processing system. Including lasers, light guide systems, processing machine tools, control systems and detection systems.

2. Laser processing technology. Including cutting, welding, surface treatment, punching, marking, scribing, micro-engraving and other various processing processes.

Laser welding: auto body thick and thin plates, automotive parts, lithium batteries, pacemakers, sealed relays and other sealed devices, as well as a variety of devices that do not allow welding contamination and deformation.2013 use of lasers are YAG lasers, CO2 lasers and semiconductor pump lasers.

Laser cutting: automotive industry, computers, electrical chassis, wood knife mold industry, a variety of metal parts and special materials, cutting, circular saw blades, acrylic, spring gaskets, 2mm or less of copper plates for electronic parts, some metal mesh boards, steel tubes, tin-plated iron plate, lead-plated steel, phosphor bronze, bakelite boards, thin aluminum alloys, quartz glass, silicone rubber, alumina ceramic pieces of 1mm or less, Titanium alloy used in the aerospace industry and so on. The lasers used are YAG laser and CO2 laser.

Laser pen

Laser pen: also known as laser pointer, finger star pen, etc., is a visible laser designed to be portable, easy to grip, laser module (diode) processed into a pen-type transmitter. Common laser pointer red (650-660nm, 635nm), green (515-520nm, 532nm), blue (445-450nm) and blue-violet (405nm), etc., the power is usually measured in milliwatts. Usually in the meeting report, teaching, guided appreciation staff will use it to project a point of light or a ray of light pointing to the object, but the laser will hurt the eyes, in any case should not let the laser directly into the eyes.

Laser therapy: it can be used for surgical openings to relieve pain and reduce infection.

Laser marking: It is widely used in a variety of materials and in almost all industries. The lasers used in 2013 are YAG lasers, CO2 lasers and semiconductor pumped lasers.

Laser perforation: laser perforation is mainly used in aerospace, automobile manufacturing, electronic instrumentation, chemical industry. The rapid development of laser perforation is mainly reflected in the average output power of YAG lasers for perforation has been increased from 400w in 2008 to 800w to 1,000w. Domestic 2013 more mature laser perforation applications are in the production of synthetic diamond and natural diamond wire drawing die and the production of watch and instrumentation gemstone bearings, aircraft blades, multilayer printed circuit boards and other industries. Most of the lasers used in 2013 were YAG lasers and CO2 lasers, with some quasi-split lasers, isotope lasers and semiconductor pumped lasers.

Laser heat treatment: It is widely used in the automotive industry, such as the heat treatment of cylinder liners, crankshafts, piston rings, commutators, gears and other parts, as well as in the aerospace, machine tool industry and other machinery industries. China's laser heat treatment applications are far more extensive than abroad. 2013 the use of lasers are mostly YAG lasers, CO2 lasers are mainly.

Laser rapid prototyping: laser processing technology and computer numerical control technology and flexible manufacturing technology combined and formed. Mostly used in molds and models industry. 2013 use of the laser mostly YAG laser, CO2 laser-based.

Laser coating: widely used in the aerospace, mold and die and electromechanical industries. 2013 used in the laser mostly high-power YAG lasers, CO2 lasers.

Laser imaging: the use of laser beam scanning object, the reflected beam reflected back to get a different order of arrangement and imaging. With the image fallout to reflect the image formed. Laser imaging has the ability to detect beyond visual range, can be used for satellite laser scanning imaging, the future for remote sensing mapping and other scientific and technological fields.
