In China, the 2008 small and medium-power laser cutting equipment market size of about 402 million yuan, with the rest of the world in 2009 by the international financial crisis, China's small and medium-sized power cutting machine market growth is slowing down. Expected in the next two years under the impetus of industrial upgrading and technological transformation of China's manufacturing industry, small and medium-power laser cutting equipment market will quickly enhance and maintain high growth. The type of laser. Laser (a laser) means light amplification by stimulated emission, is a high quality light source. Laser (LASER) is a light source of the actual invention of the 1960s. LASER is the acronym for the English "stimulated emission optical amplification". It is during the working of laser lights for sale.
Laser there are many kinds of size as large as several football fields, as small as a rice or salt. Gas lasers, helium - neon lasers and argon lasers; solid-state lasers have a ruby laser; semiconductor lasers with laser diodes, like the CD player, DVD player and CD-ROM. Each laser has its own unique laser method. The laser has many features: First, the laser is monochromatic, or single frequency. Some lasers can produce different frequencies of laser, but these lasers are isolated from each other, and separate use. Second, the laser is coherent light. The coherent light is characterized by its light waves are in sync, the entire beam is like a "wave train". Therefore, the customer can buy cheap Laser Pointers of the best quality and performance.
Again, the laser is highly concentrated, that it would go a long distance will be dispersed or convergence. Laser classification is to see from what angle, red laser, blue laser, green laser based on frequency of distinction from the principle of the He - Ne laser, CO2 laser, diode laser, excimer laser, dye laser, argon ion laser, nitrogen laser, YAG laser, and so there are many. points from the continuity of a continuous laser and pulsed laser, pulsed laser microsecond (10e-6 seconds), there are ns (10e-9 seconds), skin seconds (10e-12 seconds), and femtosecond (10e-15 seconds) laser. In addition, generally based on the intensity of the laser will be divided into one, two .... and so on. It is to digest and absorb the imported technology of laser lights for sale.
The higher the level the greater the intensity corresponding requirement is to adopt more stringent protective measures. Laser sub-band can be divided into visible light, infrared, ultraviolet, X-ray, multi-wavelength tunable, the current industrial use of infrared and ultraviolet laser. For example, the CO2 laser 10.64um infrared laser, the krypton lamp pumped YAG laser 1.064um infrared laser, the xenon lamp-pumped YAG laser 1.064um infrared laser, diode side-pumped YAG laser 1.064um infrared laser. Many different types of lasers can be divided into several types of solid, gaseous, liquid, semiconductor, and dye: solid-state lasers are generally small and sturdy high pulse radiated power, a wider range of applications. Such as: Nd: YAG laser. So that laser lights for sale has the compact structure and good quality.
Nd (neodymium) is a rare earth element, YAG behalf of yttrium aluminum garnet crystal structure with ruby. Semiconductor lasers are small, light weight, long life, simple structure, particularly suitable for use in aircraft, ships, vehicles and spacecraft. Semiconductor lasers by external electric and magnetic fields, temperature, and pressure to change the laser wavelength, can electricity directly into laser energy, so the rapid development. Gas laser gas as the working substance, monochromatic and coherent with good laser wavelength of up to thousands of wide range of applications. Gas laser structure is simple, low cost, easy to operate. Widely used in industry, agriculture, medicine, precision measurement, holography technology. And then the high quality and performance of laser lights for sale can be achieved.
