Abstract

Based on an analysis of the absorption and emission cross-section spectra of the 1%Er3+: LiNbO3 crystal in the spectral range 1450–1650 nm at room temperature the parameters of radiation-balanced generation were calculated. The optimal pump wavelength (1545 nm) and the RB generation wavelength (1610.8 nm) were determined. The corresponding efficiency and gain coefficients were calculated as F_eff=2.40×10^(-22) 〖cm〗^2 and F_gain=4.62×10^(-22) 〖cm〗^2, respectively..
