Abstract

The interaction of relativistically intense (Iλ²>>1.3 10¹⁸Wcm^-2μm²) laser pulses with a near step-like plasma density profile results in relativistic oscillations of the reflection point. This process results in efficient conversion of the incident laser to a phase-locked high harmonic spectrum, which allows the generation of attosecond pulses and pulse trains. Recent experimental results on efficiency scaling, highest harmonic generated and beam quality suggest that very high focused intensities can be achieved opening up the possibility of ultra-intense attosecond X-ray interactions for the first time.
