Abstract
Different channel optical sources are important for studies of the micro-objects and for applications in areas of the modern optoelectronics and bio-photonics. As a rule, various light micro-sources are necessary both for observe the sufficiently high spatial resolutions and also for the steady-stable coherent control in real-time during the process of organization of the high-ordered molecular systems. Experimental technique of the volumetric optical poling wherein gives possibilities for organization in isotropic mediums of the optically micro-structured elements with various properties which can be used for transformations and redistributions of pulsed light signals. In this work using the example of considering the nonlinear optical process of doubling the frequency of the pulsed laser radiation in case of the volumetric optical poling of isotropic medium it’s shown the possibility for the simultaneous and phase-matched separation of output signals of light over the paired distribution channels. Optimal conditions for selection of beams of the light signals are analyzed and the spatial and other characteristics of the channel-by-channel transformation are investigated. The work was carried out as part of Russian State Project FWGW-2025-0012.
