How does the fiber laser 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 kind of laser is fiber laser?
So a fiber laser is a type of laser which uses fiber doped with rare-earth elements (erbium, thulium, ytterbium) etc. as active laser medium. This differentiates the fiber laser to other types of laser available on the market, where the active laser medium is a crystal (e.g. disk laser) or gas (e.g. CO2 laser).
What is fiber laser technology?
A fiber laser (or fibre laser in British English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium.
What is suitable laser for fiber optics?
Lasers have proven to be ideal light sources because of their high bandwidth capability and narrow spectral output. There are 3 main types of lasers in the market today for fiber optic transmitters – VCSELs, FP lasers and DFB lasers.
Can Fibre laser cut wood?
If you’re wondering if you can use a laser machine to cut through wood materials, the answer is yes. If you’re cutting a non-organic material, you want to use a fiber laser. They have the power to cut through very hard materials such as metals and metal alloys.
How thick can a fiber laser cut?
Fiber laser cutting systems can certainly cut more than one inch thick with higher Fiber laser powers and even cut faster when utilizing nitrogen as the assist gas, but the “sweet spot” where the most significant benefits are realized is in the 1/2 inch and under range for steel when making comparisons with CO2 systems …
Are fiber lasers solid state?
Fiber lasers are one class of solid-state lasers in which the gain medium is an optical fiber. Fiber lasers have been a key technology in the area of solid-state lasers, since the first proposal of using an optical fiber as a mode selector for lasers [1].
What can a 20w fiber laser do?
20w fiber laser marking machine. It is mainly for marking on material surface, like steel, brass, coated metal. For engraving, it has capacity limit. It can not engrave too deep and engraving time will be very long. E.g. It at most can engrave 0.5mm on steel with 30 minutes or one hour.
How hot is a fiber laser?
The temperature of the low-temperature water (cooling fiber laser module) should be set at around 21 degrees Celsius. For fiber lasers above 2500W, the temperature of DI water (cooling optics) should be set between 27 degrees Celsius and 33 degreesCelsius.
How are fiber lasers made?
Briefly, fiber laser light is created by banks of diodes. The light is channeled and amplified through fiber optic cable similar to that used for data transfer. The amplified light, on exiting the fiber cable, is collimated or straightened and then focused by a lens onto the material to be cut.
Can fiber laser engrave glass?
Expensive, hand-blow glass or crystal glasses may have stresses in the material that are aggravated by the laser beam heat while engraving, which can result in fractures in the material. You can also laser process mirror glass using a fiber laser system by removing only the reflective layer on the back.
Can fiber lasers cut nonmetals?
Firstly, the fiber laser cutting machine belongs to the processing category of metal laser cutting machine. So it can only cut metal, can not cut non-metal such as cloth, leather, stone, etc. The wavelength range of fiber laser cutting machine is not within the absorption range of the above materials.
