Abstract:
We re­port on the suc­cess­ful op­er­a­tion of a Free Elec­tron Laser (FEL) in the Echo En­abled Har­monic Gen­er­a­tion (EEHG) scheme at the FERMI fa­cil­ity at Sin­cro­trone Tri­este. The ex­per­i­ment re­quired a mod­i­fi­ca­tion of the FEL-2 un­du­la­tor line which, in nor­mal op­er­a­tion, uses two stages of high-gain har­monic gen­er­a­tion sep­a­rated by a delay line. In ad­di­tion to a new seed laser, the dis­per­sion in the de­lay-line was in­creased, the sec­ond stage mod­u­la­tor changed and a new ma­nip­u­la­tor in­stalled in the de­lay-line chi­cane host­ing ad­di­tional di­ag­nos­tic com­po­nents. With this mod­i­fied setup we have demon­strated the first ev­i­dence of strong ex­po­nen­tial gain in a free elec­tron laser op­er­ated in EEHG mode at wave­lengths as short as 5 nm.
