Figure 3

The bar plots depict the normalized power measured after mode projection with a uniform-phase mask (a) or a phase-flip mask (b) for various input modes (red, top) and SFG output modes (green, bottom). The error bars due to power fluctuations are small in comparison to the systematic errors due to imperfect alignment of the SLM and projection mode. The dashed line (black) depicts the expected theoretical behavior.
