A fiber laser is a laser where the active medium being used is an optical fiber that has been doped in rare elements; typically, erbium, ytterbium, neodymium, thulium, praseodymium, holmium or dysprosium. While you don`t need to worry too much about which rare-earth elements have been used, the main thing to note is that it is fiber that is being used at the centre of this Laser Machine. This is different to the two other main types of laser, which are gas lasers (typically uses helium-neon or carbon dioxide) and crystal lasers. Fiber lasers are the newest type of laser to hit the market, with many arguing that it is the more beneficial of the three types.

Many car owners spent a happy holiday on the National Day holiday, and after returning from their cars, few owners did a “checkup†for their car. Li Taibin, head of workshop of Zidang Automobile Trading Co., Ltd., introduced: “About 30% of the cars that go out on the National Day holiday, such as the National Day holiday, will experience some problems in the chassis and tires after the self-driving tour.†Afterwards, you should check your car carefully and, if necessary, perform maintenance.
Cold Taibin introduced that returning from driving, if there is no obvious problem, it mainly checks the oil and water, chassis and tires, and the chassis and tires are the most important factors affecting daily driving safety. First of all, to check the entire vehicle's oil, coolant, glass water, etc. are normal enough, the oil quality is good, the lack of liquid surface to add, bad oil quality should be replaced in a timely manner. Also check the powertrain and the transmission system for oil leaks. Check if the engine, gearbox, rear axle, etc. of several parts have oil leakage. Secondly, the chassis was inspected. The car focused on radiators, condensers, air conditioning pipes, oil pans, suspensions, and transmission components. In addition, it is necessary to detect the tire pressure, determine whether the tire pressure of each wheel is within the normal range, and check whether the tire has been punctured or the phenomenon of cracks, check the tire tread depth and wear uniformity, and remove the pattern Stone foreign objects such as inclusions, make a four-wheel alignment.
