We know that the laser is an important part of the laser cutting machine, without it, the laser cutting machine cannot operate normally. But there are many classifications of lasers, do you understand? Let's give you a brief introduction.   There are different classification methods for the lasers of laser cutting machines, which are generally classified according to different working media, and can be divided into solid lasers, gas lasers, liquid lasers and semiconductor lasers. In addition, according to the different laser output modes, it can be divided into continuous laser and pulsed laser. The peak power of pulsed laser can be very large, and it can also be classified according to the frequency and power of light emission.   1. Solid-state lasers Generally speaking, solid-state lasers have the characteristics of small devices, sturdiness, easy use, and high output power. The working medium of this kind of laser is uniformly doped with a small amount of active ions in the crystal or glass as the host material. In addition to the ruby u200bu200band glass described above, the commonly used yttrium aluminum garnet (YAG) crystal is doped with trivalent neodymium. Ion laser, which emits 1060nm near-infrared laser. Generally, the continuous power of solid-state lasers can reach more than 100W, and the pulse peak power can reach 109W.  2. Gas laser Gas laser has the advantages of simple structure, low cost, convenient operation, uniform working medium, good beam quality, and stable and continuous work for a long time. This is also the type of laser with the most variety and wide application at present, occupying about 60% of the market. Among them, the helium-neon laser is the most commonly used one.  3, semiconductor lasers Semiconductor lasers use semiconductor materials as the working medium. At present, the more mature gallium arsenide laser emits 840nm laser. There are also lasers such as aluminum-doped gallium arsenide and chromium sulfide zinc sulfide. Excitation methods include optical pumping, electrical excitation, etc. The laser is small in size, light in weight, long in life, simple and sturdy in structure, and is particularly suitable for use on airplanes, vehicles, and spacecraft.  4. Dye lasers are commonly used for liquid lasers, and organic dyes are used as the working medium. In most cases, organic dyes are dissolved in solvents (ethanol, acetone, water, etc.), and some work in a vapor state. Different dyes can be used to obtain lasers of different wavelengths (in the visible range). Dye lasers generally use lasers as pump sources, for example, argon ion lasers are commonly used. The working principle of liquid lasers is more complicated. The output wavelength is continuously adjustable, and the wide coverage is its advantage, which makes it also widely used.   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.
