Newly Developed Solid State Lasersent when appropriate optical pumping is designed..We discuss the chemical and physical aspects of the photostability of the dyes in glasses, phenomena responsible for non radiative relaxation of their excited state, and energy efficiencies of laser.

Collective Excitations in Magnetic Materialsimensions and chain compounds for one dimensions. The form of the ground state and the excitations in lower dimensional systems are discussed for both ferromagnets and antiferromagnets. The spectroscopic methods appropriate for observing magnetic excitations are reviewed.

Optical Excitation and Relaxation of Solids with Defectspted models. An accurate description of the F. centers in alkali halides is given together with a historical account of successes and failures, the latter due to chance human events, to limited technical choices, and to a lack of scientific curiosity.

Light-Matter Interaction — Experimental Aspectshighly excited systems can be used to produce light emitting devices like laser diodes. We restrict ourselves mainly to quasistationary excitation conditions, while experimental and theoretical aspects of ultrafast spectroscopy will be treated in some of the following contributions.

The IR Vibrational Properties of Composite Solids and Particles: The Lyddane-Sachs-Teller Relation Rse functions, and very general causality arguments are used to obtain the generalized LST relation. The measured electronic excitation properties of silicon have been used to illustrate the generality of the resulting relation, which provides a useful connection between the long-wavelength dynamical
