Fig. 1. Laser pulses for (a) fast ignition and (b) shock ignition. In both cases, the compression pulse is preceded by an adiabatic shaping picket (of 100–200 ps duration) from Ref. [22].
Fig. 2. Top left: each beamlet has a phase plate to create a speckle pattern inside the focal spot. Bottom left: many beamlets overlap to smooth the focal spot. Right: introduction of adequate timing between beamlets leads to optical zooming; the spot size is changing during the pulse.
