PY - 2017 T2 - Vaughan & Asbury's General Ophthalmology, 19e AB - “Laser” is an acronym for light amplification by stimulated emission of radiation. Most light sources radiate energy in all directions, with waves that are out of phase (incoherent), and with multiple wavelengths. By contrast, laser light has a single wavelength (monochromatic) and waves that are in phase (coherent) with very little tendency to spread out (collimated), so they can illuminate with extremely high power (irradiance). A 1-watt laser produces a retinal irradiance approximately 100 million times greater than a 100-watt light bulb.
