Lasers are typically identified by their gain medium and are often classified by the radiating species that give rise to stimulated emission. These radiating species can include atoms and molecules in a dilute gas, organic molecules dissolved at relatively low concentration in liquid solutions, semiconductor materials, and dielectrics such as crystalline solids or glasses that are doped with a high concentration of ions. These laser categories are generally referred to as gas, liquid, semiconductor, and solid-state. As alluded to in Light-Matter Interactions in Lasers, the concentration of the radiating species plays a significant role in the formation of the medium’s energy levels. In turn, these energy levels will dictate the optical pumping transition, configuration for population inversion, laser emission wavelength, and gain bandwidth.
