Abstract

Aiming at developing a Ho3+-based continuous-wave ultraviolet laser, the method of determining the weight of the excited-state absorption (ESA) process occupied in the populating of the D33 level is studied. Using the rate equation model, the weight is found to be related to the weighting factors of the double-exponential decay components of the D33 level. Using time-resolved spectroscopy, the weight of the ESA process for Y2O3 ceramic doped with 0.1 mol. % Ho3+ is experimentally determined to be 83%. Furthermore, the fluorescence dynamic properties of the Ho3+-doped Y2O3 ceramic with different doping concentrations were analyzed, and the weight was found to decrease with the doping concentration but by no less than 70%.
