“…In all these laser systems, amplifiers are separated by large spatial filters. These spatial filters, using a pair of refractive lenses, are used to clean the beam of unwanted intensity modulations at high spatial frequencies 8 and also to extend and͞or to image the spatial profile on each amplifier stages. In single-pass amplifier systems, spatial filters are passed once, while in multipass amplifier configurations, spatial filters can be passed two to four times, depending on the choice of architecture.…”

Chromatism compensation of the PETAL multipetawatt high-energy laser

High-energy petawatt lasers use series of spatial filters in their amplification section. The refractive lenses employed introduce longitudinal chromatism that can spatially and temporally distort the ultrafast laser beam after focusing. To ensure optimum performances of petawatt laser facilities, these distortions need to be corrected. Several solutions using reflective, refractive, or diffractive optical components can be addressed. We give herein a review of these various possibilities with their application to the PETAL (Petawatt Aquitaine Laser at the Laser Integration Line facility) laser beamline and show that diffractive-based corrections appear to be the most promising.
