Coherent phonon frequency comb generated by few-cycle femtosecond pulses in Si
We explore the coherent phonon induced refractive index modulation of a Si(001) surface upon the excitation in near-resonance with the direct band gap of Si. Through the anisotropic e–h pair generation and coherent Raman scattering, ∼ 10-fs laser pulses exert a sudden electrostrictive force on Si la...
