    "abstract": "We study theoretical and experimentally the propagation of the angular\nspectrum of the light produced in the up-conversion process. The connection\nbetween the angular spectrum of the fundamental and the second harmonic is\nderived and measured. We show that even though they are connected, it is not\npossible to directly transfer images from the fundamental to the second\nharmonic.",
