Figure | Nonlinear synthesis of spatial coherence with nonlinear photonic crystals.

Caption

(a) Incoherent imaging of a smiley-face pattern: spatial coherence induced by an incoherent infrared light source is synthesized and transferred to visible light through second-harmonic generation. (b) Incoherent vortex beams are nonlinearly generated, doubling the orbital angular momentum from the fundamental light. (c) Incoherent Airy beams retain their self-acceleration properties, demonstrating the versatility of coherence shaping for structured light generation.
