We present a study on temperature dependent spectroscopic data for Yb:KGW, Yb:KYW and Yb:YLF between 80 K and 280 K and Yb:YAP between 100 K and 300 K. Absorption and emission cross sections are determined. The latter ones are obtained by using a combination of the McCumber relation and the Fuchtbauer-Ladenburg equation. Fluorescence lifetimes are measured within a setup optimized for the suppression of re-absorption and compared to the radiative lifetimes calculated from the previously determined cross sections to cross check the validity of the measurements. The cross sections are evaluated with regard to the materials’ potential for supporting the generation of ultra-short laser pulses, low quantum defect lasing and requirements for suitable diode laser pump sources.

用于激光应用的 Yb3+ 掺杂的 KG(WO4)2、KY(WO4)2、YAlO3 和 YLiF4 的温度相关光谱研究

我们对 80 K 和 280 K 之间的 Yb:KGW、Yb:KYW 和 Yb:YLF 以及 100 K 和 300 K 之间的 Yb:YAP 的温度相关光谱数据进行了研究。确定了吸收和发射截面。后者是通过使用 McCumber 关系和 Fuchtbauer-Ladenburg 方程的组合获得的。荧光寿命是在为抑制再吸收而优化的设置中测量的，并与根据先前确定的横截面计算的辐射寿命进行比较，以交叉检查测量的有效性。根据材料支持超短激光脉冲生成、低量子缺陷激光的潜力以及对合适的二极管激光泵浦源的要求，对横截面进行了评估。
