Abstract :
Spectroscopic characterization is carried out to identify Starkʹs levels of Yb3+ transitions in several fluoride crystals grown either by the Czochralski technique or by the laser-heated pedestal growth method. Yb3+ concentration dependence of the decay time is analyzed in order to understand involved concentration quenching mechanisms. Laser tests under saphire:Ti pumping are presented for all our materials as well as under diode pumping for Yb:CaF2.
