Me. Couprie et al., SOURCE CHALLENGES RESULTING FROM THE FIRST APPLICATIONS OF A UV STORAGE-RING FEL ON SUPER-ACO, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 375(1-3), 1996, pp. 639-643
On the Super-ACO free electron laser were developed the first applicat
ions of a storage ring based FEL and of a UV FEL. The feasibility of u
se was demonstrated in 1993 with a time resolved polarised fluorescenc
e experiment in biology. After these experiments, the stability of the
laser source was significantly improved, with the installation of a l
ongitudinal feedback. A particular advantage of a storage ring FEL sou
rce is to provide as well naturally synchronized synchrotron radiation
. A first pump-probe time-resolved experiment coupling such two tunabl
e, synchronized light sources was then performed in surface physics.
