In order to achieve this objective, we employ a laser writing system to create micro-ring arrays and subsequently cover them with a plasmonic gold thin film using a sputtering machine. Additionally, the chemical vapor deposition method is employed to generate the graphene layer. To use this medium as random laser active media, we cover it with Rh6G dye and PVP polymer as the top high index layer to get more localization of light. After theoretically and experimentally evaluating the plasmonic substrate, we use the second harmonic generation of Nd:YAG laser as the source and record the random lasing of the sample under 45° via spectrometer. Our results show that the samples without the PVP layer yield a coherent random laser with about 6 nm and 1.4 nm in the full width at half maximum (FWHM) and threshold energy of 3.17 mJ and 1.42 mJ for concentrations 10<sup>−5</sup> and 10<sup>−4</sup>, respectively, while finding that the laser threshold and FWHM are decreased by the sample with PVP layer reaching from 2.62 mJ and 5 nm to 1.95 mJ and 1.2 nm, respectively.

This study investigates the impact of multi-layer plasmonic nano-ring structures, composed of alternating layers of aluminum (Al) and nickel (Ni), on the optical current of a-Si solar cells. Using various nano-ring configurations for a cell with periods of 200 nm, 300 nm, and 400 nm, the effect of different layering sequences on photocurrent density were analyzed. Results indicate that the inclusion of nano-rings significantly boosts photocurrent density and higher layer counts yielding the greatest improvements.
