To understand the performance of fiber laser cutting machine, it is necessary to have an in-depth understanding of the laser performance of fiber laser cutting machine. So is the crackdown really clear about this issue? If it is not clear, let's follow the experts to learn. As the working medium, the laser of the fiber laser cutting machine has a long working length, which is beneficial to diode pumping, and also makes the photon conversion efficiency high, which provides conditions for a compact and robust design. When the fiber optic components are fusion spliced u200bu200btogether, there will be no discrete components that need to be adjusted.  There are some special structure fiber lasers. Fiber lasers can achieve single-channel amplification, which can simultaneously amplify light of different wavelengths and are widely used in the field of communications. Fiber amplification is also used in the MOPA structure to produce higher power laser output. Another example is the optical fiber amplified spontaneous emission source. Another example is the Raman fiber laser. Some new research is using fluoride glass fiber instead of traditional quartz fiber.   However, quartz glass is usually used to make optical fibers. The main doping elements are ytterbium (Yb) and erbium (Er). The center wavelength of Yb is between 1030 and 1080 nm, and a wide-band laser output can be obtained. Yb does not have a self-quenching effect at a very high density like Nd. Even though they can produce lasers of similar wavelengths, Nd is used in traditional lasers but Yb is used in fiber lasers.  The working wavelength of fiber laser is 1530~1620nm, which belongs to the safe wavelength band of human eyes. It can double the frequency to produce 780nm laser, which is a band that cannot be obtained in other ways. And Yb can be doped with Er, so that Yb absorbs the pump light and transmits energy to Er. Thulium is another doped element that can generate lasers in the near-infrared band (1750-2100nm), and it is also an eye-safe material.   Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment. Not only successfully developed laser equipment with advanced technology, but also used self-support import and export rights to promote products to more than forty global products including Hong Kong, South Korea, Vietnam, Malaysia, Thailand, Australia, the United States, Japan, Germany, the Netherlands, Jordan, etc. nation.
