摘要

We experimentally observe the formation of X-waves at fundamental, third harmonic, and fifth harmonic wavelengths by infrared (central wavelength at ∼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.
