Yield enhancement of elliptical high harmonics driven by bicircular laser pulses
文献摘要：
We theoretically investigate the yield enhancement of elliptical high harmonics in the interaction of molecules with bicircular laser pulses by solving the time-dependent Schrodinger equation.It is shown that by adjusting the relative intensity ratio of the two bicircular field components in specific ranges the yield of the molecular high harmonics for the plateau and cutoff regions can be respectively enhanced.To analyze this enhancement phenomenon,we calculate the weights of the electron classical trajectories.Additionally,we also study the ellipticity distribution of harmonics for different intensity ratios.We find that these enhanced harmonics are elliptically polarized,which we mainly attribute to the recombination dipole moment of the major weighted trajectories.These enhanced elliptical extreme ultraviolet and soft x-ray radiations may serve as essential tools for exploring the ultrafast dynamics in magnetic materials and chiral media.
