Laser transport properties versus focusing setting f# in arbitrary units. (a) Laser waist size calculated at 760 nm (dashed line), 800 nm (full line) and 840 nm (dotted line) with ZEMAX assuming a time-diffraction limited Gaussian beam. (b) Laser waist position relative to the wiggler center calculated with ZEMAX assuming a time-diffraction limited Gaussian beam [same line styles as for (a)] and (black circles) measured removing the wiggler vacuum chamber and using a laser power of 0.6 W with a pulse duration of 4 ps FWHM. (c) Laser power transmission from the laser amplifier output to the wiggler entrance, measured as in (b). Error bars on the black circles correspond to the precision of the measurements.
