Figure 2
Left: CCD image of the intensity distribution in the image plane. The black line indicates where the vertical intensity distribution was quantitatively analysed as shown in the right-hand figure. No beam focusing is applied in the horizontal direction. The intensity variation in this direction is caused by the limited lens aperture in this direction of 0.25–0.35 mm and by an almost identical horizontal source size. Right: normalized vertical intensity distribution, i.e. gain G, averaged over 45 CCD columns in the flat center of the one-dimensionally focused beam (black line in the left-hand picture).
