Atmospheric turbulence causes refractive index fluctuations, which in turn introduce extra
distortions to the wavefront of the propagated radiation. It ultimately degrades telescope …

The rarely considered case of laser beam propagation and focusaing through the
moderately scattering medium was researched. A phase-only spatial light modulator (SLM) …

Nonuniform irradiance profiles of lasers used in power‐by‐light systems deteriorate the
efficiency of photovoltaic laser power converters. We analyze three approaches to deal with …

Bimorph and stacked actuator deformable mirrors were used to increase the efficiency of
focusing of partially coherent laser radiation propagated through the scattering suspension …

Atmospheric turbulence causes refractive index fluctuations that introduce extra distortions
to the wavefront of the propagated radiation. It degrades the resolution of the telescope for …

Bimorph deformable mirror with the clear aperture of 50 mm and 48 control electrodes and
spatial light modulator with resolution of 1920x1080 pixels were used to increase the …

A metrological device—Hartmannometer—based on a Shack-Hartmann wavefront sensor
for measuring the flatness of optical surfaces was developed and researched, and the …

Current liquid crystal (LC) lenses cannot achieve lossless arbitrary movement of the optical
axis without mechanical movement. This article designs a novel bottom electrode through …

A multispectral wavefront sensor can be used to perform a single-shot spatio-temporal
characterization of a laser pulse. In order to measure the spatio-spectral electric field, a laser …

Laser beam shaping problem remains relevant for various applications of modern laser
physics–from laser cutting of metals to wireless long-distance energy transmission. For …
