摘要
金是一种重要的过渡金属，在学术领域具有重要的研究价值。本研究采用磁控溅射和液相剥离相结合的方法制备了金纳米粒子。通过使用纳秒和皮秒激光源的开孔 Z 扫描方法，系统地研究了金纳米粒子的非线性光学特性。基于金纳米粒子的饱和吸收特性，我们制备了金可饱和吸收体，并成功地将其分别应用于 Pr:YLF 晶体激光器和 Nd:YAG 晶体激光器中产生被动 Q 开关脉冲。我们还分析了其光学限制应用。我们的系统研究证实，金纳米粒子适合作为可饱和吸收体和光学限幅材料的候选材料。
Nonlinear absorption properties in gold nanoparticles for passively Q-switched laser and optical limiting applications
Regarded as an essential transition metal, gold holds significant research value in the academic realm. In this work, gold nanoparticles were prepared by a combination of magnetron sputtering and liquid-phase exfoliation. The nonlinear optical properties of gold nanoparticles had been systematically investigated by utilizing the open aperture Z-scan method with both nanosecond and picosecond laser sources, which were rarely involved in previous studies. Based on the saturation absorption properties of gold nanoparticles, we prepared a gold saturable absorber and successfully applied it in generating passively Q-switched pulses in Pr:YLF crystal laser and Nd:YAG crystal laser, respectively. And we also analyzed its optical limiting applications. Our systematic study confirms that gold nanoparticles are suitable as candidates for saturable absorbers and optical limiting materials.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
