    Diffraction pattern of LN NPC with Sierpinski fractal superlattices.
    Illustration of the experimental setup.
    Second, third, and fourth harmonics by nonlinear diffractions in an LN NPC at a fundamental wavelength of 1997 nm. (a) Photos of centric red harmonic and its linear diffraction, and multiple harmonics. (b) Illustration of the multiple harmonics.
    Phase-matching diagram in nonlinear Čerenkov radiation. (a) Čerenkov second-harmonic o and e wave radiations. (b) Čerenkov second-, third- and fourth-harmonic waves.
    Čerenkov radiation conical angle as a function of the input fundamental wavelength. The gray, red, and green lines correspond to Čerenkov second, third, and fourth harmonics. The solid and dotted lines correspond to generated o and e Čerenkov harmonics. Top: outside LN NPC; bottom: inside LN NPC.
    Phase-matching diagram in cascaded FHG process (No. 4).
    Phase matching diagram in two kinds of cascaded FHG processes (No. 5).
