Laser Induced Fluorescence Line Narrowing Studies of Praseodymium in Lanthanum-Trifluoride and Application of Pressure Scanning to the Tuning of a High Resolution Dye Laser.
Abstract
Different applications of pulsed tunable dye lasers to solid state spectroscopy are discussed. It is shown that time-resolved fluorescence line narrowing is one of the most suitable and versatile methods to investigate the spectroscopic properties of solids. Investigations included not only the low concentration limit, but also samples of higher concentration. By sampling the fluorescence signal very shortly after the excitation pulse, measurements of homogeneous widths were undertaken. It is shown that the effect of accidental coincidence plays an important role in the analysis of nonresonant linewidths at low temperatures. Also to be considered are differences in the dependence of the excited state energies on the crystal field strength.
