A projection of an erbium-doped active-fiber laser is offered in this research paper. Mode synchronization method — the nonlinear evolution of mode polarization, is used to ensure the duration of femtosecond pulses. The basis of this method uses liquid crystal controllers polarization, which is controlled by an electrical signal. The proposed scheme and method for obtaining ultrashort pulses are free from the unstable operation of the laser.

It was shown that the combined use of photodynamic therapy of different wavelengths (red λ = 660 nm, green = 530 nm, blue λ = 440 nm), hematopoietic stem cells and platelet growth factor is an effective treatment for purulent-septic complications, which can be considered as a new technology for correcting afferent and efferent immunoreactivity in patients with chronic purulent wounds that are not susceptible to antibiotic therapy.

Neuromorphic computing is a field of electronics that uses the similar principles as human brain does. In this paper we show that a spin Hall oscillator based on an antiferromagnetic dielectric material can operate as a terahertz-frequency neuron in neuromorphic schemes. Also, we show that such AFM-neurons can execute most of the logical operation.

A systematic study of the properties of the output dark rays or singular skeleton for the Laguerre-Gaussian beam LG01 passed through double-phase-ramp converter is presented. When the DOE is discontinuous at the origin, as is the case here, the transfer function is not analytical, so that a special theoretical approach is needed. The previously reported formalism of scattering modes, which permitted the analytical calculation of arbitrary multisingular Gaussian beams, requires analyticity everywhere. We present here an adaption of this formalism that overcomes this limitation. The procedure is based on the differential operator algebra used in the previous construction. We give an example of diffraction of LG beams by a discontinuous DOE that can be solved completely in an analytical way using this adapted method. The experimental setup for the investigation of the considered problem with spatial light modulator is discussed. The theoretical and experimental skeletons are similar but not the same because initial conditions are slightly different. In the near future, we plan to obtain analytical solutions that reproduce exactly the initial field parameters used in the experiment.

Nowadays, the processing of data obtained as a result of airborne laser scanning by a group of unmanned aerial vehicles includes up to eight different stages. From the point of view of organizing such processing, it is reasonable to use modern cloud technologies. The paper proposes a new method for processing this type of data based on the social model of completing game quests. Portions of data arrive at a computing system consisting of several clouds where, in turn, multifunctional SaaS nodes operate. Each of the nodes can process one data portion once, which allows to exclude the principle of exclusive use of one node for all stages of processing a data portion. The paper proposes an original algorithm for determining the optimal node for the next stage of processing, which takes into account: the time of data portions movement between SaaS nodes, in fact, processing and waiting in the node queue. Due to carried out experiments, it was found that the implementation of the developed quest method allows to reduce the workload of SaaS nodes by the uniform distribution of processing between all nodes, which was to an average of 30%. Additionally, in the case when the number of processing nodes is less than three, the efficiency of the method decreases to zero. This paper suggests that the ques method can also be used on board of the nodes of a flying sensor network during airborne laser scanning of the area in rapid-response systems.

Directive properties of monopole nano-antenna formed by carbon nanotube placed perpendicularly to metal rectangular screen are investigated. On the base of the method of the uniform geometric diffraction theory the asymptotic solution of the 3D vector problem of diffraction of the field of impedance monopole with radius r and length l placed on the ideally conducting rectangular screen is obtained. The fast-active algorithms and software for calculating 3-D patterns of this radiating system are developed. Analysis of the radiation patterns and directivity versus the screen sizes is carried out.

We demonstrate the stable and robust operation of an all-polarization-maintained ultra-high frequency Fabry–Pérot cavity passively mode-locked fiber laser. The laser operates in an all anomalous-dispersion solitonic regime, generating a 1GHz pulse train. The cavity of the laser is configured by a single fiber of a single type, highly doped and polarization maintaining. Its propierties are studied by a variety of measurements, which confirm the high stability of the laser in the spectral–both optical and electrical-domains. Pulse durations of 2.55ps, optical spectrum stability < 0.3dB, average power output of 105mW and long-term uninterrumped operation during 48h with 0.25% variation (standard deviation) in the average output power are obtained. In the RF domain, 100dB signal-to-noise ratio are measured at 200kHz offset from the fundamental harmonic frequency. The theoretical validation of our experimental results is based on solutions of the Nonlinear Schrödinger Equation.
