Abstract

The effects of topological semimetal MoP nanosheets and MoP quantum dots as saturable absorbers on Er-doped lasers were investigated. Experimental results revealed a modulation depth of 3.2% and a pulse width of 1.31 ps when MoP nanosheets were employed as the saturable absorber. In contrast, MoP quantum dots exhibit superior performance, achieving a modulation depth of 17.2% and compressing the output mode-locking pulse width to 668 fs. Furthermore, a simulation model was developed to validate the consistency of the mode-locking output characteristics of MoP saturable absorbers with the experimental findings. Those results indicate potential application prospects for MoP nanomaterials in future ultrafast optics.

基于MoP纳米片和量子点的可控掺铒锁模光纤激光器

研究了拓扑半金属MoP纳米片和MoP量子点作为饱和吸收剂对掺铒激光器的影响。实验结果表明，MoP纳米片作为饱和吸收剂时，调制深度为3.2%，脉冲宽度为1.31 ps。相比之下，MoP量子点表现出更好的性能，实现了17.2%的调制深度，并将输出锁模脉冲宽度压缩到668 fs。此外，建立了仿真模型，验证了MoP饱和吸收器锁模输出特性与实验结果的一致性。这些结果预示着MoP纳米材料在未来超快光学领域的潜在应用前景。
