Abstract
We have studied the modes of formation of channel proton-exchange waveguides in periodically polarized gradient lithium niobate with Yb3+ and Er3+. Using this approach here, it is possible to provide conditions for phase quasi-synchronism along activated Yb3+, Er3+:PPLN in such a way that at the initial stage of amplification, power take-off to the second harmonic will be minimal, increasing along the length of the converter. Thus, it is possible to increase the conversion efficiency and provide amplification of the optical signal and its conversion in one element of the activated Yb3+ and Er3+ gradient PPLN.
