Abstract

Nonlinear X-shaped angle-wavelength spectrum of the generated second-harmonic wave is observed for a collimated femtosecond pulse of a large beam waist, where the spatiotemporal balance is originated from mutual coupling of the effective nonlinear Kerr effects, pulse frequency chirp, and negative phase shift from cascaded quadratic processes with appropriate phase mismatch.
