Lasers can be useful not only in the obvious "hardware" application for the generated "soup" composition controlling by different methods of laser spectroscopy, but also in the generation of perspective hypotheses
Inexpensive device for particles (that commit Brownian movement in liquid) dimensions measurement by analysis of scattered light autocorrelation function was designed, made and tested. The device comprises obtainable elements, analogue-to-digital conversion is performed be common sound blaster PC card, numerical data processing was made by specially developed software. Testing results for different...
The paper is devoted to theoretical modeling, fabrication, and advanced spectroscopic characterization of circuits of microspheres with high quality whispering gallery modes (WGMs). The discussion of results is based on three mechanisms of optical coupling between spherical cavities: (i) resonant coupling between WGMs in identical cavities, (ii) Fano resonance between a discrete energy state (true...
The influence of the input signal temporal profile on output spectra of running wave amplifying interferometer (RWAI) is studied by mathematical modeling with the aim to make use of RWAI in terahertz spectroscopy. Two ways are considered: two frequency signal obtaining for further difference frequency signal extracting and reception of the required frequency as the spectrum component of sinusoidal...
We propose a novel concept of optical delay lines where the tunable delay can be achieved by controlling the inter-resonator gap sizes in circuits of optically coupled microspheres.
This paper describes the fabrication, characterization and spectroscopic properties of novel structures made from prearranged circuits of optically coupled polystyrene microspheres in a robust elastomeric polymer.
In this paper the evaluation of correspondence of angle of synchronism naturally tuning device for CARS stimulation by signal of parametric generator is presented
