Schematic of COP generation mechanisms. (a) Impulsive stimulated Raman scattering (ISRS), (b) displacive excitation of coherent phonons (DECP), and (c) ultrafast screening of surface depletion electric field. (c) Reproduced with permission from from ref (426). Copyright 1992 Springer-Verlag. (d) Nonlinear ionic Raman scattering (IRS) process. The red, magenta, and olive patterns correspond to the phonon manifolds of the material, pump laser profile, and induced COP profile, respectively.
