Controllable ultrabroadband supercontinuum during twocolor femtosecond laser filamentation in high pressure gases
Yury E. Geints, Victor O. Kompanets, Sergey V. Chekalin
Twocolor laser filamentation is considered a promising strategy for deep transformations of the spectrum and generating ultrashort light pulses, which is critically important for d…
Measurements of Optical Kerr Nonlinearity n2 in Compressed Gases
Yury E. Geints, Victor O. Kompanets, Sergey V. Chekalin
High-power optical pulses experience self-focusing when propagating in a gaseous medium due to the manifestation of the cubic (Kerr-like) nonlinearity. The magnitude of this effect…
Study of size and shell composition effect of TiO2 core-shell mesoporous microsphere on UV absorption effectivity for photocatalytic application
Yury E. Geints, Ekaterina K. Panina
Microdispersed photocatalysts based on titanium dioxide (TiO2) in the form of hollow core-shell microspheres (microcapsules) with mesoporous structure are widely demanded in modern…
Boosting Light Absorption of a Therapeutic Microcapsule by Means of Auxiliary Solid Nanoparticles
Yury E. Geints, Ekaterina K. Panina
Multilayer microparticles with a liquid core and a polycomposite light-absorbing shell are important components of modern bio- and medical technologies, in particular, as transport…
Phase-dependent Supermode Excitation in Photonic Molecules
Yury E. Geints
A photonic molecule (PM) is a miniature diffractive optical structure composed of resonance microcavities called atoms (e.g., cylinders or spheres) supporting a set of high-quality…
Enhanced optical trapping assisted by resonant energy backflow in a perforated dielectric microsphere
Yury E. Geints, Igor V. Minin, Oleg V. Minin
Optical energy flow inside a dielectric microsphere exposed to an optical wave is usually codirected with its wave vector. At the same time, if the optical field in a microparticle…
