High-Harmonic Generation and Correlated Electron Emission from Relativistic Plasma Mirrors at 1 kHz Repetition Rate
摘要
We report evidence for the first generation of XUV spectra from relativistic surface high-harmonic generation (SHHG) on plasma mirrors at a kilohertz repetition rate
emitted simultaneously with energetic electrons. SHHG spectra and electron angular distributions are measured as a function of the experimentally controlled plasma density gradient scale length Lg for three increasingly short and intense driving pulses: 24 fs and a0 = 1:1
8 fs and a0 = 1:6
and finally 4 fs and a0 ≈ 2:1
where a0 is the peak vector potential normalized by mec/e with the elementary charge e
the electron rest mass me
and the vacuum light velocity c. For all driver pulses
we observe correlated relativistic SHHG and electron emission in the range Lg ∈ ½λ/20
λ/4
with an optimum gradient scale length of Lg ≈ λ/10. This universal optimal Lg-range is rationalized by deriving a direct intensity-independent link between the scale length Lg and an effective similarity parameter for relativistic laser-plasma interactions.
