Laser-active ions

WebIn the stimulated emission process, the laser-active ions are made to emit light in the direction of already existing light, and also with the same optical phase . The resulting amplitude and phase profile of the laser beam is largely determined by the properties of the laser resonator, not by the laser gain medium. WebThe luminescence center of most laser crystals is composed of activated ions which replace the cations in matrix crystals to form doped laser crystals. When activated ions become part of the matrix crystal components, they form a self-activated laser crystal. Following are laser crystals owned by Laser-crylink Er:YAG Ti:Sapphire Nd:YAG Nd:YVO4

Ion laser - Wikipedia

WebThe laser-active ions are typically doped into the core of the optical fiber which is a glass host material. The most common dopant ions are the rare-earth elements of Yb, Er, and Tm whose laser gain bandwidths can be seen in Figure 3. Virtually all fiber lasers are optically pumped by laser diodes or other fiber lasers. A krypton laser is an ion laser using ions of the noble gas krypton as its gain medium. The laser pumping is done by an electrical discharge. Krypton lasers are widely used in scientific research, and in commercial uses, when the krypton is mixed with argon, it creates a "white-light" lasers, useful for laser light shows. Krypton lasers are also used in medicine (e.g. for coagulation of retina), for the …
