Abstract:
The absorption and emission cross-section spectra of LiNbO3:Tm3+ crystals were investigated within the wavelength range of at room temperature. This study delves into the potential for achieving radiation-balanced lasing. Optimal parameters for both the pump and emission wavelengths, denoted as and , respectively, were determined. At these wavelengths, the corresponding optimal values for gain and radiation-balanced generation efficiency were identified. These findings underscore the feasibility of radiation-balanced lasing in LiNbO3:Tm3+ crystals under the specified conditions.
