TL;DR: In this paper, two types of optical metamaterials operating at near-IR and mid-IR frequencies, respectively, have been designed, fabricated by nanoimprint lithography (NIL), and characterized by laser spectroscopic ellipsometry.

TL;DR: In this article, cross-laser and molecular beams were used to obtain the recoil-energy distributions of fragments in the study of multiphoton dissociation of SF 6, and the measured recoil energy distributions were in good agreement with the theoretical prediction of the RRKM model for unimolecular dissociation assuming an average excitation of ≈ 22 kcal/mole beyond the dissociation threshold and complete energy randomization in the excited molecule before dissociation.

TL;DR: In this article, the authors present a review of the history of self-focusing and self-trapping of optical beams, as well as some important papers from the past.

TL;DR: In this article, the bulk contribution to surface sum-frequency generation (SFG) from an isotropic medium is investigated and a practical method for the analysis of spectra obtained in a transmission geometry is presented.

TL;DR: In this article, a multiphoton dissociation of various halogenated hydrocarbons by laser beams is reported and the statistical theory of unimolecular reactive is found to be adequate to explain the process.
