Figure 1.7.3.19

Calculated angular tuning curves. θ and $[\varphi]$ are the spherical coordinates of the phase-matching directions. θ^d is the phase-matching angle of the degeneracy process ( $[\lambda_i^d=\lambda_s^d=2\lambda_p]$ ). $[\lambda_i^o]$ and $[\lambda_s^o]$ are the idler and signal wavelengths, respectively, generated at θ^o. Ordinary and extraordinary refer to the polarization.
