Abstract

We report on an experimental study of the “coherent” contrast feature that frequently appears in petawatt(PW)-class laser pulses as an exponentially-rising pedestal within a few tens of picoseconds of the compressed pulse. We show that scattering from the diffraction gratings in the stretcher is the principal source of this feature. Replacing the gratings by new, higher-quality components resulted in an order-of-magnitude reduction in the intensity of the pedestal.

Fig. 4

Diagrams of the Astra pulse stretcher: (a) plan view; (b) side view. Labelled components are: first grating (G1); spherical mirror (SM); second grating (G2); back mirror (BM). The dashed outline in (b) indicates the tilted position of the spherical mirror that was used to bypass the second grating and the back mirror. Part (c) shows a plan view of the prism and mirror arrangement that was used as a substitute for the first grating in the tilted mirror configuration.

Comparison of contrast scans with different configurations of the stretcher. Red trace: second grating and back mirror bypassed. Blue trace: prism and mirror in place of first grating. The grey background trace was recorded with the normal configuration of the stretcher.

The coherent pedestal recorded with the original stretcher gratings (blue trace) and the new gratings (red trace).
