Fiber lasers are widely used for cutting, welding, marking, engraving, and cleaning. Many industrial fiber laser systems operate in the near-infrared range, commonly around 1064nm to 1080nm.

These wavelengths are generally invisible to the human eye. Unlike a visible laser, there may be no obvious visual indication that the beam is present.

Fiber laser safety glasses use specialised filters designed to attenuate the wavelengths produced by the laser. The appropriate protection depends on the specific wavelength and operating conditions of the equipment.

Laser safety glasses should be considered as part of a broader safety system. Enclosures, beam controls, interlocks, warning systems, restricted access, and appropriate training may also be required depending on the application.

Anyone operating or working around a high-power fiber laser should understand the hazards associated with the specific system and use appropriate controls and protective equipment.
