Figure 12
Simple concave modification: beam expansion to (a) 5 µm, (b) 10 µm, (c) 15 µm and (d) 21 µm at mirror's focal point (approximately 0.4 m downstream from center of mirror). Black curves with dots are measured profiles. Thick solid red curves are best-fit super-Gaussians. Values of p and R2 are shown in labels. Note the large beam sizes, but also the high striation level indicated by the low goodness of fit R2.
