Fiber lasers are a type of laser that uses optical fibers to amplify and transmit light. They offer several benefits and advantages over other types of lasers.
The fiber laser was created in response to production needs increasingly based on automation and the search for high performance to maintain competitiveness in the market. It is a solid-state laser in which the laser beam is amplified by an optical fiber “pumped” through diodes. The fiberglass is doped with elements such as erbium, neodymium, or ytterbium; the particular concentration of these metals, therefore, makes it possible to amplify and guide the laser radiation.
Advantages of Fiber Laser Machines
1. Versatility across sectors: Fiber lasers are used in almost every sector such as aerospace, and automotive including e-mobility, dental, electronics, jewelry, medical, science, semiconductor, sensor systems, solar, and others.
2. High efficiency: Fiber lasers are very efficient, with typical conversion efficiencies of around 25-30%. This means that they convert a high percentage of the input power into output power, resulting in lower operating costs and reduced energy consumption.
3. Compact due to the small installation area: Fiber lasers are compact and space-saving They are therefore ideal for manufacturing where there is a shortage of space.
4. High beam quality: Fiber lasers have a high beam quality, which means that the laser beam is focused into a smaller spot with a more uniform intensity distribution. This is important for many applications, such as cutting and welding, where precision and accuracy are critical.
5. Compact and rugged design: Fiber lasers have a compact and rugged design, making them easier to integrate into existing systems and less susceptible to damage from shocks and vibrations.
6. Long lifespan: Fiber lasers have a long lifespan, with some models capable of operating for tens of thousands of hours without requiring maintenance or replacement.
7. Versatility: Fiber lasers can be used for a wide range of applications, including cutting, welding, marking, engraving, and drilling, making them versatile tools for many industries.
8. Lower cost: Fiber lasers are perfect for reducing overheads and operating costs. They are a cost-effective solution with a good price/performance ratio and have extremely low maintenance costs. Fiber lasers can be manufactured at a lower cost than other types of lasers, making them more accessible to a wider range of applications and industries.
9.Large material range:
Fiber lasers have the ability to process many different materials. Metals (including mild steel, stainless steel, titanium, and reflective materials such as aluminum or copper) make up the majority of laser processing applications worldwide, but plastics, ceramics, silicon, and textiles are also being processed.
10.Low energy efficiency:
Fiber lasers are highly efficient and consume less power than conventional manufacturing machines. This reduces your carbon footprint and lowers your operating costs.
Overall, fiber lasers offer a range of benefits and advantages that make them a popular choice for many industrial and scientific applications.
Which type of laser should be used for metal cutting
The best laser cutting machines for metals are fiber lasers, followed by CO2 lasers. The type of laser cutter most suitable for a metal application depends on factors such as: the specific metal and its reflectivity, the metal’s melting and vaporization temperatures, and the workpiece’s thickness. The type of metal and its reflectivity determines whether a fiber or CO2 laser is better for cutting. This is because metals readily reflect long red and infrared wavelengths that are commonly emitted by CO2 lasers. Metals absorb shorter blue, violet, and ultraviolet wavelengths from fiber lasers. The melting and vaporization temperatures and the thickness of the workpiece determine the minimum power required for cutting as more power and energy density is required to cut through thicker materials.
