Exponential growth of self-amplified spontaneous emission (SASE) at 530 nm has been experimentally observed** at the Advanced Photon Source low-energy undulator test line (LEUTL). Since then further detailed measurements and analysis of the results have been made. Here we present the measurements and compare these with calculations based on measured electron beam properties and theoretical expectations.
