研究目的
Investigating the preparation and characterization of the ReS2 nanosheet based saturable absorber and its applications in Nd:YSAG lasers, including the anisotropic property of the ReS2 nanosheets at 1.06 μm.
研究成果
The ReS2 nanosheets demonstrated good saturable absorber properties in Nd:YSAG lasers, with a maximum power output of 356 mW and minimum pulse widths of 523 ns and 435 ns with different output couplers. The anisotropic property of ReS2 nanosheets at 1.06 μm was confirmed, showing potential for use in opto-electronic devices.
研究不足
The study focuses on the ReS2 nanosheets' application in Nd:YSAG lasers and their anisotropic properties at 1.06 μm, potentially limiting the generalizability to other wavelengths or materials.
