ABSTRACT: Paeonia species are important ornamental plants, including three types: tree peony, herbaceous peony, and Itoh hybrid peony. Paeonia with yellow color is desired and becoming popular. However, the chemical mechanism of the formation of yell

We investigate the triggering and guiding of DC high-voltage discharges over a distance of 37 cm by filaments produced by ultraviolet (266 nm) laser pulses of 200 ps duration. The latter reduce the breakdown electric field by half and allow up to 80%

Optical parametric chirped-pulse amplification (OPCPA) using high-energy Nd:glass lasers has the potential to produce ultra-intense pulses (>1023 W/cm2). We report on the performance of the final high-efficiency amplifier in an OPCPA system, based on

We experimentally verify an analytic model that includes alignment errors for the output pulse from divided-pulse nonlinear compression. The model shows how divided-pulse nonlinear compression can simultaneously broaden the pulse spectrum and improve

Anthocyanins and flavonols have vital roles in flower coloration, plant development, and defense. Because anthocyanins and flavonols share the same subcellular localization and common biosynthetic substrates, these pathways may compete for substrates

Filament-induced periodic surface structures are generated on a wide variety of materials with near-IR and UV lasers. The surface structure features demonstrate the relation to laser wavelength and polarization and energy distribution in a filament.
