Tunability and tolerance of optical parametric oscillator in periodically poled lithium niobate

Based on analyzing the operating principium of optical parametric oscillator (OPO) in periodically poled lithium niobate,the tunability of the signal/idler wavelength on the periodically poled grating period,the pump wavelength and the bulk temperature were given in this work.Furthermore,the dependence of the gain of OPO on the grating period,the crystal temperature,and the pump wavelength were analyzed by solving the differential coefficient of the phase dismatched factor.Also the dependence of the gain of OPO on the tolerance of the bulk temperature,the pump wavelength and the grating period was given.
