摘要：
The paper presents the results of an experimental study of the efficiency of coupling of waveguide structures formed in a lithium niobate crystal by the optical induction method. The waveguides were produced by soliton laser beams with wavelengths of 532 and 457 nm at different optical powers. Estimation of the efficiency of coupling of the obtained structures for infrared radiation with a wavelength of 850 nm was more than 70%.
