What type of materials do fiber lasers cut effectively?

Fiber lasers are known for their effectiveness in cutting reflective materials, such as aluminum and copper, which are challenging for other types of lasers due to their reflective properties. Unlike CO2 lasers that typically struggle with these materials, fiber lasers utilize a different wavelength that is absorbed better by metals, leading to efficient cutting capabilities.

Reflective materials can dissipate heat easily, but fiber lasers have a high beam quality and can generate intense energy concentration, allowing them to cut through these materials effectively. This makes them a preferred choice in various industrial applications where precision and efficiency are required.

Options mentioning only soft materials, exclusivity to thicker metal sheets, or being limited to plastics and rubber do not fully capture the versatility and effectiveness of fiber lasers across a broader range of materials, including those that are reflective.
