Embodiment 1

[0024] A method for preparing a metal nanomesh based on electronic dynamic regulation, the specific steps are as follows:

[0025] Step (1) Use the femtosecond laser 1 to generate a horizontally polarized femtosecond laser pulse with a repetition rate of 1000 Hz and a wavelength of 800 nm, and enter the structured light path of the Michelson interferometer through the first mirror 2 and the second mirror 3 . Rotate the angle of the quarter-wave plate 9 to 0°, at this time, the two sub-pulses of the double pulse generated by the Michelson interferometer are both horizontally polarized, and a fluorescent sheet is placed before the exit of the Michelson interferometer to observe the two sub-pulses For the light spot after the space overlap of the pulses, adjust the one-dimensional translation stage 6 to adjust the time delay of the two sub-pulses. When the light spots on the fluorescent sheet after the space coincidence of the two sub-pulses start to flicker, adjust to the positio...

Compared with the traditional processing method, the present invention does not need masks, templates, etc., and the process is simple and the cost is low.

Description

technical field [0001] The invention relates to a method for preparing a metal nano-network based on electronic dynamic regulation, and belongs to the technical field of laser applications. Background technique [0002] The metal nano-network structure is a micro-nano structure whose size scale is on the order of nanometers, and its structure size is between tens of nanometers to tens of nanometers. With the rapid development of micro-nano technology, the preparation of metal nano-network structures has attracted extensive attention due to its great application prospects in the fields of wettability, surface-enhanced Raman scattering, structural color surfaces, and solar cells. At present, the methods for preparing metal nano-network structures include template-assisted method, vapor-liquid-solid direct growth method, photolithography and thin film deposition method, etc. However, these methods often require complex processes, expensive devices and harsh processing environm...
