摘要: A nonlinear refractive index n2.DAN of a 4‐(N, N‐dimethylamino)‐3‐acetamidonitrobenzene (DAN) single‐crystal cored fiber 3.9 mm length and 2.3 μm core radius is evaluated by observing the spectral broadening 250 fs pulse due to dispersive self‐phase modulation in its that conventional fused‐silica fiber. The result shows value femtosecond‐response nonabsorbing wavelength region around 625 nm 1.7×104 times as large latter’s glass
