Figure 1.7.3.4

Index surface sections in a plane containing the optic axis z of a negative uniaxial crystal allowing collinear type-I phase matching for SFG ([\omega_3=\omega_1+\omega_2]), [\gamma = 3], or for SFG ([\omega_4=\omega_1+\omega_2+\omega_3]), [\gamma = 4]. [{\bf u}^{\rm I}_{\rm PM}] is the corresponding phase-matching direction.
