Collective Excitations in the Optical Spectroscopy of Magnetic Insulatorsel excitons play a major role in the absorption structure near the electronic origin of d-d absorption in transition metal ion compounds or of f-f absorption of rare-earth materials. Both pure exciton and exciton-magnon transitions are observed below the magnetic ordering temperature. These provide

Optical Excitation and Relaxation of Solids with Defectsthis century. Color centers display an optical cycle that very often produces luminescence having a very high efficiency after excitation and relaxation. This optical characteristic has been utilized for the last 20 years to produce color center lasers, with a high spectral purity emission tunable f
