摘要:Almost all attention has been paid to the effective nonlinear coefficient along the direction of phase matching, so this paper calculated the omnidirectional effective nonlinear coefficient of ReCOB single crystals by computer out of interest. The results showed that the distribution of the first and second quadrants of omnidirectional vertical bar d(eff)vertical bar presented multi-peaks surface divided by three "valleys" which were made up of a series of minimum values. The variation of d(32) and d(13) had more significant impacts on the distribution of omnidirectional vertical bar d(eff)vertical bar than the other coefficients and the variation of wavelength had negligible influence on that. A broadband wavelength range about 6 nm could achieve efficient frequency conversion simultaneously within the deviation being less than 2 degrees during a type-I DFG process in YCOB crystal. These results could provide valuable guidance for the selection and utilization of ReCOB crystals.
