Induced Compton scattering in current high-power laser facilities

Shuta Tanaka (Aoyama gakuin University)

We focus on one of the fundamental laser-plasma nonlinear interaction, called induced Compton scattering, which is expected to occur in some astrophysical situation such as pulsar magnetosphere. The brightness temperature of the Crab pulsar’s radio emission has attained to 10^37 K and then the Crab pulsar is considered as the laser facility in nature. The radio signal from the Crab pulsar can be modified by induced Compton scattering. We introduce possible experiments of induced Compton scattering in present laboratories. Further understanding of induced Compton scattering will be an interesting tool to resolve the long-standing problem of the astrophysics, i.e., the radiation mechanism of the pulsar emission.
