WebLuminescence and the nature of light A hot body that emits radiation solely because of its high temperature is said to exhibit incandescence. All other forms of light emission are called luminescence. When luminescence occurs, the system loses energy and if the emission is to be continuous, some form of energy must be supplied from elsewhere. flow advertisement

"WebA laser only emits light of high irradiance at a very narrow wavelength interval, typically under 0.01 nm, which makes an excitation monochromator or filter unnecessary. The disadvantage of this method is that the wavelength of a laser cannot be changed by much. A mercury vapor lamp is a line lamp, meaning it emits light near peak wavelengths.
