Figure 6: Conical refraction for a circularly polarized Gaussian input beam with R0/w0 = 10.
From: Extreme Ultraviolet Fractional Orbital Angular Momentum Beams from High Harmonic Generation

Images (a,c,e) are cuts of the intensity pattern in the yz plane at x = 0 showing the space evolution of the CR beam, the B0 component, and the B1 component respectively. Images (b,d,f) show the transverse intensity distribution obtained at the focal plane of the CR beam, the B0 component, and the B1 component, respectively.
