Abstract

A Yb(3+)-doped mixed-perovskite single crystal (La, Sr)(Al, Ta)O(3) (LSAT) crystal is grown by the Czochralski method. The absorption spectrum, fluorescence spectrum and fluorescence lifetime of Yb(3+) ions have been investigated, and the spectroscopic parameters of Yb:LSAT have also been calculated. This crystal exhibits a remarkably large ground-state splitting (about 1100 cm(-1)), a relatively long fluorescence lifetime (0.85 ms) and broad absorption and emission bandwidths. The results indicate that the Yb(3+):LSAT crystal is a good candidate for diode-pumped ultrashort and tunable solid-state laser applications.

摘要

采用提拉法生长了掺镱（Yb(3+)）的混合钙钛矿单晶（La，Sr）（Al，Ta）O(3)（LSAT）。研究了 Yb(3+)离子的吸收光谱、荧光光谱和荧光寿命，并计算了 Yb:LSAT 的光谱参数。该晶体表现出显著的基态分裂（约 1100 cm(-1))、较长的荧光寿命（0.85 ms）和较宽的吸收和发射带宽。结果表明，Yb(3+):LSAT 晶体是二极管泵浦超短和可调谐固态激光器应用的理想候选材料。
