INVESTIGATION OF FORMATION OF CHANNEL WAVEGUIDE STRUCTURES WITH DIFFERENT TOPOLOGY IN SURFACE AREA OF ELECTRO-OPTICAL CRYSTALS
The experimental results of possibilities of formation of channel waveguide structures with different topologies by laser radiation in lithium niobate samples, surface-doped by copper (Cu) and iron (Fe) ions, or their combinations, are demonstrated. The obtained structures are point-by-point induced at light wavelengths λ = 532 nm and λ = 450 nm with low powers in continuous mode.
