Fiber Laser vs Infrared Laser vs UV Laser

Fiber, Infrared (IR) laser and UV laser are easily confused. Many beginners even make the mistake of thinking that they are the same laser source, but the truth is that the three lasers have different wavelengths and uses. The truth is that the three lasers have different wavelengths and services.
The fiber laser has a wavelength suitable for engraving/cutting metals, the IR laser has a long wavelength suitable for material processing, and the UV laser has a short wavelength suitable for processing semiconductors.
This article will provide a comprehensive overview of how fiber, IR, and UV lasers work and their similarities and differences. It will help you learn more about these lasers to make a better choice of machine.

What is a fiber, Infrared (IR), or UV laser source?

Fiber laser sources are solid-state laser sources that utilize a fiber core and dopant elements as the main components of the laser source. The structure of a fiber laser source can be divided into three parts: the outer cladding, the inner cladding, and the innermost dopant element. The fiber core guides electrons through the dopant elements and becomes photons with the same wavelength.
Infrared (IR) lasers and fiber lasers are both solid-state laser sources. However, IR lasers work differently from fiber lasers in that IR lasers do not have core or dopant elements as a medium but instead use air as a medium.
The UV laser source differs from both in that it usually uses gases, semiconductors, and solids as the activation medium. The wavelength of the UV laser source is between 100-400nm.
