Topical Problems of Laser Crystal Physicsy in certain activated crystals (Y.A1.O. and YA1O.) are included. In addition, the 3μm stimulated emission of Er. (.I. → .I. transition) and Ho. (.I. → .I.) ions at 300 K is covered. Finally, the new laser operating scheme of self-saturating transitions, and lasers with deactivator ions (e.g. Lu.A1.O.: Er., Tm.) are also discussed.

Generalized Excitations in Pure Ionic Crystals, the basic properties of a generalized excitation in a quantum-mechanical system are discussed. The general theory is applied to three special cases: optical phonons, Frenkel excitons and magnons. The interactions among these different types of excitations are also presented and discussed.

Polaron Theory Applied to Luminescent Point and Associated Impuritiescase within the adiabatic approximation for which the lattice responds to the stationary distribution of electronic particles is analyzed separately from the polaron case in which the lattice follows the orbital motions of the electronic particles. Some applications to specific materials are considered.
