heal.abstract	This work explores the potential of laser excited luminescence for the study of type and concentration of rare-earth (RE) luminescence centres in CaF2. A comparison with X-ray excited luminescence is made. The luminescence spectra of several natural and synthetic samples are obtained at low and room temperatures using different Ar+ and Kr+ laser lines for excitation. Tentative assignment of the luminescent lines to different RE2+ and RE3+ ions is made. The excitation is shown to take place predominantly through the emission of one phonon. The possibilities for concentration measurements of luminescent centres are discussed. © 1988 Springer-Verlag.	en
