Type of laserWe can divide the types of laser, according to the characteristics of the laser medium are as follows:• Gas Laser: laser intermediary substances, gas, such as CO2 Laser is a Laser, Argon, Xenon, Laser He-Ne Laser.• Solid State Laser: the laser medium used is a solid Crystal Nd: YAG rods, Laser, a Ruby Laser.• Dye Laser: the intermediate substance is a liquid such as 6G Rhodamin Laser.• The Semiconductor Laser: a laser, a laser-based intermediary compounds as Semiconductor Laser Diode for various types.The laser is used in industrial work in pat จับัน: He-Ne Argon-Ion Carbon dioxide Laser, Laser, Laser, Laser Nd YAG Laser: Ruby, Semiconductor Laser, and Laser Eximer.4. applications of laserWe can apply the laser to applications in many aspects. As follows:1. industrial:• Cutting and Marking laser is applied to cause a scratch or cut material. The laser beam is controlled by going to fall to pieces with a computer program. Generally, laser cutting and marking system is divided into 2 major template is: (1) the moving parts, which can make a mark, or cut materials with high resolution as well. For example, the mark on the ICS, etc., and (2) a moving beam system (flying optics), which is used in systems with a large working area and high power laser. The advantage of using this type of work in the laser is no heat accumulation in the material. Make the material flexibility does not occur after making the cut.• Welding or welding is to use the heat of the laser beam and 2 pieces of molten material into the same body where the laser beam.The advantage of using a laser to weld welding spots are able to make very small, such as the gold line connections from chips, laser systems, miscellaneous forests and ICS. In addition, the heat accumulated in the material, it is extremely rare due to the high power consumption during the very short time so it can control and customize the features of surface area as well as welds.• Drilling or drilling in General, uses very small hole drilling or the use of high strength materials such as ceramics.
