Propagation effects in resonant high-harmonic generation and high-order frequency mixing in laser plasma
Vasily V. Strelkov, Margarita A. Khokhlova
We study the phase matching of resonant high-harmonic generation (HHG) and high-order frequency mixing (HFM) in plasma. We solve numerically the propagation equations coupled with…
