Abstract
The present invention provides in a Free electron laser a means to increase the temporal resolution of the optical pulses while simultaneously increasing the spectral resolution of the pulse train. The increase in temporal resolution is achieved by introducing a quadratic temporal phase variation (i.e. linear frequency chirping) across the pulses, and then propagating the outcoupled pulses through a dispersive relay line to compress them to the transform limit of the broadened spectrum.
