Effects of plasmonic gap mode formation due to coupling between metal nanoparticles and thin metal film separated by thin dielectric luminescent film-spacer (gap) have been studied by means of light extinction and photoluminescence in three-layer pla

Optical properties of a plasmonic metasurface made of a monolayer of gold nanoparticles in close proximity to an aluminum thin film were studied numerically and experimentally. Extinction spectra o...

Plasmonic nanoparticles can be used to engineer radiation decay of a dipole in close proximity to the surface of the particle. In this talk I will review our recent theoretical and experimental results on the enhancement and quenching of radiation fr

Accurate modeling of the operation of diode-pumped alkali lasers is a critical step toward the design of high-powered devices. We present precision measurements for the Cs-CH4 62P3/2 → 62P1/2 mixing cross section and the 62P3/2,1/2 → 62S1/2 quenc

We examined the performance of potassium diode pumped alkali laser (K DPAL) using He, Ar, Methane (CH4), Ethane (C2H6) and a mixture of He and CH4 as a buffer gas to provide spin-orbit mixing of the 4P3/2 and 4P1/2 states of Potassium atoms. We found

We have examined fine-structure mixing between the rubidium $5^{2}P_{3/2}$ and $5^{2}P_{1/2}$ states along with quenching of these states due to collisions with methane gas. Measurements are carried out using ultrafast laser pulse excitation to popul

Diode Pumped Alkali Laser (DPAL) is one of the main candidates for development of a high power directed energy system producing laser beam from a single aperture with high spatial quality. Currently, several groups in the US and abroad demonstrated D

We modeled a sandwiched structure ZnO/VO2/ZnS potentially as a VO2-based smart window with a goal to increase both luminous transmittance (Tlum) and solar modulation ability (ΔTsol). Compared to the previously used single-layer antireflection coatin
