As the oxidation reaction in the cutting process produces a lot of heat, the energy required for laser oxygen cutting is only 1/2 of the melting cut. This makes it useful as a cutting and cauterizing instrument. Table 1. That is to use the laser to heat the metal material surface to achieve surface heat treatment. The machine requires isolation from the earthquake focus and ensure that the laser is in dry and constant temperature. Applications in Medical applications, welding and Cutting, surveying, garment industry, laser nuclear fusion, communication, laser printing, CDs and optical discs, spectroscopy, heat treatment, barcode scanners, laser cooling. A change in surface composition, organization, and performance that is not achieved by the large surface quenching. In manufacturing, lasers are used for cutting, bending, and welding metal and other materials, and for ‘marking’ i.e. The temperature rises rapidly and reaches the boiling point of the material in a very short period of time. The laser beam bounces off a rotating mirror and scans the code, sending a modulated beam to a light detector and then to a computer which has the product information stored. Other common applications of lasers are bar code readers, laser printers and laser pointers. In optical fibre communications, lasers are used as light source to transmit audio, video signals and data to long distances without attenuation and distortion. Ohanian quotes a factor of 10 advantage for the laser modulators. Laser engraving works with a laser beam with extremely high energy density under the control of the computer, irradiate the surface of the product which required marking to make the surface of the product melt or vaporize instantly, thus marking the product surface with the required text or logo, as shown in figure 4. Lasers are widely used in manufacturing, e.g. The cutting cost is large and the subsequent processing cost is higher. The second largest application is fiber-optic communication. Because of laser processing technology has many advantages, laser in industrial manufacturing shows that the low cost, high efficiency and application of the huge potential, make the world’s major industrial countries compete with each other.

The content can be numbers, letters, Chinese characters, graphic images, barcodes, etc. At the same time, the manufacturing industry needs to meet the ever-changing needs of the users, and also requires the manufacturing technology to be more flexible, which can be produced in small batches or even single parts without increasing the cost of the product. This reduces the average power output by 50%. The comparison of several marking techniques. A focused laser can act as an extremely sharp scalpel for delicate surgery, cauterizing as it cuts. With the acceleration of the global market integration process, the competition of the manufacturing industry is very fierce, and the development speed of products becomes the main contradiction of competition. If a better pulse shape can be maintained, then the communication can be sent at higher rates without overlap of the pulses. Select 14 - Lasers in dermatology. Then apply a certain pressure, the brittle material will crack along the slot. The principle of laser oxygen cutting is similar to that of oxyacetylene cutting. And because it does not belong to the contact welding process, the loss and deformation of the fixture can be minimized. The CO2 laser generator is discharging through a mixture of CO2, He and N2 in the cavity of the laser by high pressure. But laser welding also has many disadvantages, which include: (1) The position of the welding parts should be very precise and must be within the focus range of the laser beam. In various fields, laser cutting, laser marking and laser welding are the most widely used. Your email address will not be published. Your email address will not be published. These shafts are manufactured to high precision, and if the entire camshaft is heat treated, some warping will inevitably occur. Fiber optic cables are a major mode of communication partly because multiple signals can be sent with high quality and low loss by light propagating along the fibers. One recent NASA accomplishment was a successful exchange of laser pulses with the MESSENGER spacecraft and an Earth-based observatory which set a new record for laser transmission in space. Finally, laser treatments of the retina, vitreous humour, lens, ciliary body, iris, irido-corneal angle, cornea, sclera, conjunctiva and eyelid are described, with emphasis on the applications for treatment of diseases. The programmed cutter can cut dozens to hundreds of thicknesses of cloth, and can cut out every piece of the garment in a single run. It is an extension of laser technology in industrial application. Laser scribing utilizes laser with high energy density to scan the surface of brittle materials, heat the material into a small groove. The laser fusion cutting does not require the complete vaporization of the metal, the required energy is only 1/10 of the vaporization. for cutting, drilling, welding, cladding, soldering (brazing), hardening, ablating, surface treatment, marking, engraving, micromachining, pulsed … The highly collimated beamof a lasercan be further focused to a microscopic dot of extremely high energy density. IPG’s Thulium fiber laser has demonstrated positive outcomes for this application. Laser cutting, laser engraving and laser marking gains more and more acceptance on the market. (13) You can switch the device to transfer the laser beam to the multi-workstation. The process simply involves the use of a focused laser beam (e.g. Our mission is to foster lasers, laser applications, and laser safety worldwide. (8) Easy to weld in high-speed and automatically, or controlled by digital or computer. From the initial principle technology development stage to the practical application field. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Application of laser: Laser are used in many various field. The liquid metal is ejected by the powerful pressure of the gas, forming an incision. Engraving or marking can be added to an object to increase its aesthetic value, complete a product or to have a more practical function, such as adding a barcode. A fiber laser generator uses a glass fiber doped with rare earth elements as a gain medium. The cauterizing action is particularly important for surgical procedures in blood-rich tissue such as the liver. Small cutting seam (high utilization rate), There is no mechanical stress in the incision, There is no need to process or simply process after welding. If it was off for ½ second and on for ½ second that would be referred to as a 50% duty cycle. Laser cutting is to use the focused high power density laser beam to illuminate the workpiece, so that the material that is irradiated rapidly melts, vaporizes, ablates or reaches the point of ignition. The highly collimated beam of a laser can be further focused to a microscopic dot of extremely high energy density. The energy of the laser radiation diffuses through the heat conduction to the material, and the material is melted down to form a specific molten pool. 9 CLINICAL APPLICATION OF GaAlAs 830 NM DIODE LASER (LLLT) IN TREATMENT OF RHEUMATOID ARTHRITIS. It also has higher environmental requirements (less dust). Two of the most common applications that lasers can also perform are laser marking and laser engraving. Laser processing technology (FIG. The high temperature produced by the laser is used to sintered metal powder in 3D graphics, producing metal components. (4) The laser beam can be easily focused, aligned and guided by an optical instrument. When machining, the incision is smooth because it replaces the traditional tool or flame with a light beam. Garmire points out an interesting application of CO2 lasers to the welding of stainless steel handles on copper cooking pots. A fiber laser can cut thin copper plates.
