We have demonstrated a diode-pumped Yb:LiYF(4) (Yb:YLF) laser oscillator for the first time to our knowledge. A wide tuning range of 25 nm and a high slope efficiency of 50% were obtained at a high laser-diode pump intensity of 100 kW/cm(2). Emission and absorption spectra of the Yb:YLF crystal at 8 K represent a wide laser gain width of 38 nm, indicating efficient laser operation similar to that of a four-level laser system with a reduced saturation fluence of 11 J/cm(2).
据我们所知，我们首次展示了一种二极管泵浦的Yb:LiYF₄（Yb:YLF）激光振荡器。在100 kW/cm²的高激光二极管泵浦强度下，获得了25 nm的宽调谐范围和50%的高斜率效率。Yb:YLF晶体在8 K时的发射和吸收光谱显示出38 nm的宽激光增益宽度，表明其激光运行效率高，类似于饱和通量降低至11 J/cm²的四能级激光系统。
