Anti‐Stokes signals at the near‐ultraviolet wavelength are efficiently generated based on degenerate four‐wave mixing by coupling the femtosecond pulses into the fundamental mode of a photonic crystal fibre. When the pump pulses with the central wavelength of 840 nm and the average power of 300 mW are used, the conversion efficiency η s of the anti‐Stokes signal at 432 nm can be up to 40℅, and the pulse width is measured to be 42 fs by the Talbot effect.
