EXPERIMENTAL CHARACTERIZATION OF SEEDED FEL AMPLIFIER AT THE NSLS SDL

Creators

Description

Experimental characterization of a near-IR FEL amplifier at the NSLS SDL is presented in this report. SASE was observed from 0.8-1 (micro)m with 5 orders of magnitude gain. We have experimentally demonstrated saturation of a laser seeded FEL amplifier and control of the FEL output by the seed laser. Nonlinear harmonics have also been explored. The FEL pulse length for the first three harmonics was experimentally characterized and the increase of the FEL pulse length with harmonic number was observed for the first time. Computer simulation confirmed that the observed wide spectrum of the laser seeded FEL is due to the positive chirp of the seed laser
