Jp. Feve et al., EXPERIMENTAL-STUDY OF WALK-OFF ATTENUATION FOR TYPE-II 2ND-HARMONIC-GENERATION IN KTP, IEEE journal of quantum electronics, 31(8), 1995, pp. 1569-1571
We present an experimental study of walk-off attenuation for Type II S
HG, concerning both weak and strong focusing, In particular, we study
1.064 mu m SHG in KTiOPO4 (KTP). The optimum focusing conditions and s
aturation length are well described by the Gaussian model contrary to
the plane waves approximation. The saturation of the associated angula
r acceptance is clearly put in evidence for the strong focusing cases.
