The continuous development of nanotechnology has brought new trends of thought and new impetus to sculpture art. In the field of microengraving, people usually use two-photon engraving technology, but not every particle conforms to the engraving process. ZnO nanoparticles have a high refractive index and are extremely flexible, making them the material of choice for laser engraving. This article aims to investigate whether the incorporation of high-refractive-index flexible nanoparticles into engraving techniques can significantly improve the functional properties of products. This paper firstly introduces the preparation methods of common nanoparticle laser engraving materials and then describes simple micro-nano sculptures on this basis. Finally, experiments on the transmittance and refractive index of ZnO nanoparticles are carried out. The experimental results show that the refractive index and transmittance of this material are 1.7 and 1.039, respectively, which is very suitable for laser engraving.

A generalized theoretical model of the formation of a thermoelastic photoacoustic signal from real materials is proposed taking into account the presence of defects and impurities. An effective coefficient of thermal expansion was introduced that describes the dilatation effect of thermally activated lattice irregularities. Expressions for the thermoelastic photoacoustic signal obtained in the linear approximation were applied to describe aluminum membrane vibrations at the periodic laser excitation measured in other studies using a gas-microphone open-cell photoacoustic technique. The proposed theoretical model allows us to explain the experimental results in the 20 Hz–7 kHz modulation frequency range without invoking the assumption of the bulk absorption of pump laser radiation in aluminum membranes.
