Abstract

Angular multiplexing is the concept of using many temporally short pulselets stacked back to back for propagation through an amplifier chain so that the amplifier’s energy is extracted efficiently. Even though the pulselets are distinguished in both time and spatial propagation direction, in the amplifier the propagation can be approximated as a very long pulse propagating along the central axis of the amplifier. Recently it has been suggested that the pulselets should have a specific shape which conforms to laser fusion target requirements. The question that resulted from this idea was what front-end pulse shape is required to yield the desired output pulse shape from the last amplifier.
