| Abstract: | Quasi-phased-matching technique is a rapidly growing field due to recent advances in the fabrication of periodically-poled ferroelectric materials and is widely used in frequency conversion, such as optical parametric oscillation ( OPO) , difference frequency generation, sum frequency generation, and second harmonic generation. In optical parametric oscillation based on PPLN, the output wavelengths are conveniently tuned by changing operating temperature and the grating periods of periodically poled lithium niobate ( PPLN ) . We program to calculate the output wavelengths of OPO pumped by wavelength at 1 064. 2nm with different grating periods of PPLN 28. 5um, 29. 0 um and 29. 5 um, while the operating temperature changes from 250K to 550K. The influences of PPLN periods on the signal wavelength of OPO under the condition of pump wavelength at 1064nm and operation temperature at 100 C are analyzed in detail. |
