Abstract

A tunable continuous wave (CW) Yb:CaWO4 laser operating in near infrared (NIR) spectral region is demonstrated by pumping with a diode laser. Continuously broadband tunable wavelengths are obtained in two polarizations by rotating the Lyot filter. The tuning widths of the output wavelengths in the π- and σ-polarizations are 42 nm (from 1005.2 nm to 1047.2 nm) and 41.8 nm (from 1005.1 nm to 1046.9 nm), respectively. At an absorbed pump power of 15.6 W at 976 nm, the maximum output powers in the π- and σ-polarizations are 5.2 W at 1026.2 nm and 4.7 W at 1028.1 nm, respectively. To the best of our knowledge, this is the first tunable laser operation by using Yb:CaWO4 crystal.
在近红外光谱区工作的可调谐连续波 Yb:CaWO4 激光器
通过使用二极管激光器泵浦,演示了在近红外(NIR)光谱区工作的可调谐连续波(CW)Yb:CaWO4 激光器。通过旋转 Lyot 滤波器,可在两个偏振中获得连续的宽带可调谐波长。输出波长在 π 偏振和 σ 偏振下的调谐宽度分别为 42 nm(从 1005.2 nm 到 1047.2 nm)和 41.8 nm(从 1005.1 nm 到 1046.9 nm)。在 976 纳米波长吸收泵浦功率为 15.6 W 时,π 极和σ 极的最大输出功率分别为 1026.2 纳米波长的 5.2 W 和 1028.1 纳米波长的 4.7 W。据我们所知,这是首次使用 Yb:CaWO4 晶体进行可调谐激光操作。
