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).
Can you cut with a fiber laser?
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.
Does fiber laser need gas?
Why do we need auxiliary gas when we use a fiber laser cutting machine to cut metal materials? There are four reasons: we use auxiliary gas when using a fiber laser cutting machine. 1. First, the assist gas will chemically react with the metal material to increase the working capacity.
How long does a fiber laser last?
Life Expectancy of These Machines Apart from that, most of the laser in the market have a life around 30,000 hours, which is a lay man’s language is 15 years of proper usage. Further, one can expect a good 100,000 hours life of fiber lasers, which roughly translates to 45 years of machine use.
Do fiber lasers lose power over time?
Laser power will likely decrease over time because laser optics and mirrors gradually absorb more laser light.
What can fiber lasers 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.
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 reason is very simple. And the ideal cutting effect not achieve.
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.
How much does a fiber laser cost?
Fiber lasers usually cost in the range of $20,000 to $45,000. Don’t get too caught up in the high priced fiber laser machines.
Can a fiber laser cut copper?
Fiber laser cutters are also a strong choice for cutting copper because they can cut a versatile thickness of materials, from thin to thick.
Can a fiber laser cut metal?
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 a fiber laser cut plastic?
Fiber lasers are known for their ability to quickly and easily mark a range of materials, from metals to plastics.
Can a laser cut a human?
Unlike other ordinary light sources, laser cutting lasers can achieve energy concentration due to their monochromaticity, coherence, collimation and high energy density, thus causing damage to human organs (especially human eyes). .
What can a 30w fiber laser cut?
30w fiber laser marking machine For cutting, most of customers cut gold and silver. 30w also has much good performance on that. It can cut maximum 0.7mm silver and 1mm gold. Based on those, no matter on performance, but also on cost, 30w is also the most popular type.
What is the difference between Fibre laser and CO2 laser?
The main difference that determines the type of materials each laser can process is the wavelength. A fiber laser usually has a wavelength of 1,060 nm while CO2 lasers have wavelengths in the 10,600 nm range. In general, fiber lasers have many advantages over CO2 lasers.
How thick can a 150 watt laser cut?
Excellent for small-batch manufacturing (18″ x 32″ cut area), the Universal 150W is simple to use and can cut or engrave the following materials: wood (up to 1/2″ thick) metal (marking only) acrylic (up to 1/2″ thick).
How deep can a fiber laser cut?
Fiber Laser cutting equipment can cut stainless steel below 4mm, and can cut up to 8 ~ 10mm thick stainless steel in laser beam if add oxygen.
How much power does a fiber laser use?
Very low power consumption A 3000W fiber laser requires 10kW of electrical power plus 5kW for a chiller with a total of 15kW. $2,700 per year 15kW per hour at 12 hr. shift An equivalent 4000W CO2 laser and chiller combination could be as high 250kW for operation.
What materials Cannot be laser cut?
Unsafe Material for Laser Cutter Material: Danger: PVC (Poly VinylChloride) /vinyl/pleather/artificial leather Emits pure chlorine gas when cut! ABS Emits cyanide gas and tends to melt Thick ( >1mm ) Polycarbonate/Lexan Cut very poorly, discolor,catch fire HDPE/milk bottle plastic Catches fire and melts.
Can a fiber laser engrave acrylic?
Both CO2 and fiber lasers will mark cast acrylic, but their end result is quite different. With a fiber laser, clear acrylic won’t mark but the results on black acrylic can be stunning as it marks with an almost pure white image.
What is the best wood to laser engrave?
Make Alder your top choice for laser engraving projects. Cherry – A blonde cherry wood has a high resin content and is typically light in color. Although it has high levels of streaking, cherry is still an excellent choice for many laser etching projects. Maple – This is an excellent wood for engraving photos.
