8.7: Lasers - Physics LibreTexts
WEBSep 12, 2022 · A laser is device that emits coherent and monochromatic light. The light is coherent if photons that compose the light are in-phase, and monochromatic if the photons have a single frequency (color). When a gas in the laser absorbs radiation, electrons are elevated to different energy levels.
Laser science - Wikipedia
WEBLaser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser.
