Tuning the orbital angular momentum of high harmonics by manipulating the collinear photon channels in two-color high-harmonic generation
The characteristics of the photon channels in the collinear two-color high-order harmonic generation (HHG) are investigated with the vortices. It is found that the yields of the photon channels sensitively depend on ratio of the intensities I_{2ω}/I_{ω}. This sensitive dependence exhibits unique cha...
