Spectral and Laser Characteristics of Activated Crystals, various quantum processes occurring in the activated medium with the radiation field. Basic to this connection are the energy transitions between different activator levels, which determine whether electromagnetic energy is absorbed or emitted by the medium. In his famous paper in terms of ther

Operating Schemes and Types of Lasers Based on Activated Crystals, In one four-level scheme, the terminal level for the induced transition belongs to the ground state of an activator ion and is rather low (Fig. 3.1c); this scheme of operation usually requires deep cooling of the crystal. In another variant of the four-level scheme, the induced transition terminate
