TL;DR: In this article, two mutually coherent laser beams intersect at the surface of a coated substrate, creating a sinusoidal intensity profile, which is then transferred into the holographic film, creating the line and space pattern with spatial period.

TL;DR: In this paper, the authors proposed a laser marking method that does not cause micro-cracking and is suitable for marking on a hard transparent material and includes the steps of disposing a sample of a target material while providing a space from a specimen of a material which can be marked, directing an irradiation beam having an energy fluence greater than the ablation threshold of the target material so that at least a part of the targeted material is ablated and consequently is thrown up onto the surface of the material which could be marked.

TL;DR: Wang et al. as discussed by the authors proposed a flexible surface plasmon resonance (SPR) film, a method of performing Surface enhanced Raman Spectroscopy (SERS), SPR, film, and a SERS system.

TL;DR: In this paper, the field lines of Poynting vector around a small particle are investigated on the basis of classical Mie theory, where a particle can effectively absorb incident energy from its surrounding regions, resulting in a great increasing in its optical absorption crosssection, which could be much greater than its geometrical cross-section.

TL;DR: In this article, a self-similar cascade of three nanocrescents with progressively decreasing sizes and separations was proposed, and the maximum E-field enhancement factor of over 105 was obtained with both polarizations of perpendicular and parallel to the axis of the chain, which is larger than the single crescent.
