Laser-active ions
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 …

WebAug 17, 2024 · The theoretical description of the operation of radiation-balanced lasers based on the set of coupled rate equations is presented and discussed. It is shown that, for athermal operation, the value of the pump wavelength of the laser must exceed the value of the mean fluorescence wavelength of the RE laser active ions doped in the laser medium. WebAn optical fiber becomes active by doping its core with one or more rare-earth ions. Some ions of the host medium are replaced by the trivalent rare-earth ions of the same valence and similar size, to reduce the influence of the host lattice on the wavelengths, bandwidths, and cross sections of the relevant optical transitions 3.
