What is fiber laser source?
A fiber laser is a type of solid-state laser that uses an optical fiber as a gain medium. The core in the center of the fiber is doped with a rare-earth element, Yb (ytterbium), and has the highest refractive index. A 1.1 μm Laser light and Pump light propagate in this Yb-doped center core.
How does a fiber laser source work?
Fiber lasers use pump light from what is called laser diodes. These diodes emit light that is sent into the fiber-optic cable. Optical components located in the cable are then used to generate a specific wavelength and amplify it. Finally, the resulting laser beam is shaped and released.
What material can a fiber laser cut?
Fiber can cut copper, brass and aluminum much better and more safely than CO2 because the beam is more readily absorbed and not reflected. Fiber laser operating costs are typically half of what a CO2 system can offer due to the lower electrical consumption and high electrical efficiency of Fiber lasers.
How does fiber laser cutting machine work?
Fiber Laser Cutting Machine Working Principle The laser cutting of metal mostly adopts high power carbon dioxide continuous laser generator. When cutting, spray the inert gas flow, blow out the incision to melt the metal, and make the incision smooth and straight. The jet’s oxygen flow will increase the cutting speed.
Can laser be formed in an optical Fibre?
Unlike most other types of lasers, the laser cavity in fiber lasers is constructed monolithically by fusion splicing different types of fiber; fiber Bragg gratings replace conventional dielectric mirrors to provide optical feedback.
What is the difference between a YAG laser and a fiber laser?
Unlike YAG lasers, fiber lasers utilize semiconductor diodes as the pumping mechanism and a doped fiber optic cable as the gain medium. In a fiber laser, the doped fiber optic serves as the resonator. The many pros of a fiber laser include: Highest beam quality.
Can fiber laser cut steel?
Which laser sources can be used to cut metal? In general, it is possible to cut metal with both CO2 and fiber laser. Metals such as steel or ferrous materials can be cut more easily than light or non-ferrous metals such as copper or aluminum.
Can fiber lasers cut?
While fiber laser is excellent at cutting most materials, because of the shorter wavelength it cannot cut acrylic or polycarbonate and can only cut wood or fabric in limited applications. Another consideration is the thickness of material to be cut.
