Laser Safety IPG Photonics supplies our unique line of fiber lasers and amplifiers to systems integrators as well as directly to end-users. Because IPG provides products to a variety of end users, it is our desire to provide basic information on the topic of laser safety. This information is being provided as a service to both our existing customers and perspective customers. Please see the links at the end of this section for additional sources of information concerning laser safety. Lasers/amplified light sources produce light that does not exist in nature. A stimulus such as high intensity light is input into a laser cavity and the result is laser emission or light output. Although the output is light, the laser/ amplified light is much different that sunlight or a light bulb. Therefore because laser/amplified light has special properties there are often hazards associated during operation and potentially during service. Lasers/amplified light sources produce highly intense monochromatic light which can be visible or invisible to the human eye. Laser/amplified light is also coherent which means that all of the waves are in phase with each other. Coherence makes this light much more dangerous than non-coherent light of the same wavelength and intensity. Collimated beams or beams that do not diverge rapidly as they exit the device aperture have risks that are present even at long distances from the aperture.
