中文摘要	we experimentally observe the formation of x-waves at fundamental, third harmonic, and fifth harmonic wavelengths by infrared (central wavelength at similar to 1500 nm) femtosecond laser pulse filamentation in air. by fitting the angularly resolved spectra of the fundamental and harmonic waves using x-wave relations, we confirm that all the x-waves have nearly the same group velocity, indicating that they are locked in space and time during their propagation in filament.
