Powerful attosecond pulses from relativistic mirrors

Relativistic Mirrors are an extremely promising route to generating high power attosecond radiation pulses in the XUV. The underlying principle relies on the temporal compression and upshifting of optical radiation when reflected from a relativistic reflector. Practical relativistic mirrors rely producing an electron sheet with a Lorentz factor γ>;>;1. Practical demonstration of relativistic mirrors is with can be produced with the ult be done by two Different approaches (Oscillating and Flying Mirror) will be discussed both theoretically and experimentally.
