1. Properties of frequency-drift pulse amplification

The schematic diagram of the CPA technique is shown in figure 1 . The output beam of a mode-locked oscillator, consisting of a train of short pulses [AF 3 282] , is sent into a dispersive system. The phase term associated with dispersion then causes a temporal broadening and frequency drift of the pulses, which can then be amplified efficiently, limiting the risk of optical damage. Compression is then achieved by applying...
