About Laser
Laser, the essential part inside of a high-end fiber laser cutting machine, which depends on the final qualification for laser machine. Are you familiar with the principles of Lasers?
 
 
 
Fiber lasers are doped fiber amplifiers that provide light amplification without lasing. In 1953, Charles Hard Townes and graduate students James P. Gordon and Herbert J. Zeiger produced the first microwave amplifier which is highly coherent. In 1958, A.L.Schawlow and C.H. Towns extended the principle of microwave amplifiers by stimulated emission of radiation (maser) into visible light, called “optical maser.” In 1960, T.H. Maiman and other scientists produced the first functioning laser. In 1961, Ali Javan and his workmates constructed the first gas laser: HeNe laser. In 1962, R.N. Hall created the first laser diode device, which is made of gallium arsenide.
 
The above demonstrates the history of lasers; people divide laser into four categories at present: gas laser, solid laser, the semiconductor laser, and dye laser ion in terms of operating principles. Besides, it comes out recent innovations of a variety of improved and specialized laser types including free-electron laser (FEL) and pulsed operation of lasers.
 
Generally, the high-power laser cutting machine existed on the market uses a pulsed output laser, which requires more on the working medium and is expensive.

What is the pulsed laser?
The pulsed laser works by stimulated radiation, that light is amplified.  It has advantages of excellent monochromaticity, minimal divergence, and high brightness. Therefore, the level of brightness depends on the power level.
 
The largest laser power on the market is 15KW, G3015HF-15000W launched by HAN’S LASER, Han’s Laser Smart Equipment now has the competence to produce high-power laser source.
Although laser technology now in producing fiber laser cutting machines of 15KW or higher. Higher laser power has difficulties in mass production; it will be overcome soon.
