Herein, we present aN Er-doped all-fiber laser with BiVO as the saturable absorber (SA). To illustrate the nonlinear optical response, a two-dimensional model of monoclinic and its electronic structure was calculated. The nonlinear absorption properties were evaluated utilizing the Z-scan technique, and a saturable absorber was fabricated for integration into a fiber laser, resulting in a stable Q-switched output. At a maximum pump power of 600 mW, the fiber laser achieved an average output power of 25.23 mW and a pulse energy of 330.76 nJ. This research confirms that BiVO material exhibits outstanding nonlinear optical characteristics, thereby broadening its scope of application in the realm of ultrafast pulsed fiber lasers.
在此，我们展示了一种以BiVO作为饱和吸收体（SA）的掺铒全光纤激光器。为了说明其非线性光学响应，计算了单斜晶系的二维模型及其电子结构。利用Z扫描技术评估了非线性吸收特性，并制作了一个饱和吸收体用于集成到光纤激光器中，从而实现了稳定的调Q输出。在最大泵浦功率为600 mW时，该光纤激光器实现了25.23 mW的平均输出功率和330.76 nJ的脉冲能量。这项研究证实，BiVO材料具有出色的非线性光学特性，从而拓宽了其在超快脉冲光纤激光器领域的应用范围。
