Λi phasematching Λs Figure 3.18: Different predicted higher order spatial mode phasematching contours ously excited JSAs, as plotted in Figure 3.19 and 3.20. These measurements are in good qualitative agreement with our modelling, yet it is difficult to find a quantitative accordance. The waveguides are not rectangular and the pump pulses incident into the crystal don not show the assumed properties. Hence further investigations in theory and experiment have to be made. 18
