High-order harmonic generation from controlled plasma mirrors

摘要

Ultrashort, high contrast laser pulses when focused to high intensity and reflected from a steep solid density “plasma mirror (PM)” contain coherent XUV radiation in the form of high-order harmonics. The emission can either be due to the relativistically driven oscillating PM (ROM) [1] or due to Coherent wake emission (CWE) [2]. Selective control over the mechanisms and the characteristics of these harmonics and understanding the physics is crucial for the development of intense attosecond light sources.
