| 中文摘要 | the authors report the measurement of the angularly resolved spectrum of the third harmonic generated in a femtosecond filament in air and its evolution with increasing pump power. pumped by a focused infrared ultrashort pulse with a carrier wavelength of 1270 nm, a pulse duration of similar to 20 fs, and pulse energy up to 487 mu j, the generated third harmonic is composed of an on-axis emission and a conical ring emission. when the pump power is sufficiently high, angularly resolved spectra with significant x-like feature could be observed, indicating the formation of nonlinear x wave at third harmonic.
