研究目的
Investigating the generation of high-intensity attosecond pulses by the interaction of two counterpropagating short laser pulses with underdense plasma.
研究成果
The study demonstrates that intense attosecond pulses can be generated under optimized conditions of plasma density and driver laser amplitude, with the frequency of the source pulse upshifted significantly. The findings are in agreement with the relativistic similarity theory and suggest potential applications in attosecond spectroscopy and the study of electron dynamics.
