A fiber laser is a solid-state laser in which an optical fiber doped with rare-earth ions acts as the gain medium. Pump diodes inject light into the fiber, the doped core amplifies it through stimulated emission, and an optical resonator builds ...
What Is a CO2 Laser? A CO2 laser is a type of laser that uses a mixture of carbon dioxide, nitrogen, and helium gas to generate a beam of light strong enough to cut or engrave materials like wood, acrylic, and leather. It's one of several laser...
If you're not yet familiar with the basic principle behind all lasers — light amplified through stimulated emission — start here: What is a Laser and How Does It Work? Beyond that shared foundation, laser machines diverge sharply bas...
A laser is a device that produces a tightly focused beam of light through a process called stimulated emission. Unlike light from a bulb or the sun, laser light travels in one direction, at a single wavelength, with its waves moving in step with...
