倍半氧化物晶体被认为是高功率超快激光器的有前途的增益介质，其荧光光谱的加宽可以缩短可实现的激光脉冲，对应于峰值功率的增强。在这项研究中，我们证明了扩大的倍半氧化物的荧光光谱的电子-声子耦合效应和配体工程与Lu 2 O3主机的声子能量和掺杂浓度的不敏感性的优势。Yb：LuxY 2-xO 3（0
Sesquioxide crystals were identified as promising gain media for high-power ultrafast lasers, and the broadening of their fluorescence spectra could shorten the achievable laser pulses, corresponding to the enhancement of the peak powers. In this study, we demonstrate the broadening of the fluorescence spectra of the sesquioxides with the electron-phonon coupling effect and ligand engineering associated with the advantages of the Lu2O3 host in the phonon energy and insensitivity to doping concentrations.
