Investigation of crystal field effects for the spectral broadening of Yb³⁺-doped Lu _x Y_2-x O₃ sesquioxide crystals.

ABSTRACT: The investigation of crystal field effects is significant for elucidating the spectral characteristics of Yb³⁺-doped sesquioxide crystals for ultrafast laser generation. The narrow spectra of Yb³⁺-doped single sesquioxide crystals limit the generation of ultrafast lasers; in this study, the Y³⁺ ions were introduced into Lu₂O₃ single crystals by the employment of ion replacement to broaden the spectra. To analyze the spectral broadening, the responsible crystal field parameters (CFPs) were calculated. The conversion of the host dominant ion and the distortion of the ligand affected the values and signs of the CFPs, and further determined the energy level splitting and fluorescence spectra. A linear relationship expressed by the semi-emp
