Extended Data Fig. 1

(a) Experimental setup for HHG by coherent radiation and BSV. (b) Photon-number distribution of BSV. The solid line is a theoretical fit, which corresponds to single-mode BSV, the only fitting parameter being the mean photon number (dashed line). (c) Measured averaged FROG trace of BSV.
