Abstract
We carried out spectroscopic studies on the supercontinuum radiation from the plasma channels generated by femtosecond laser pulses propagating in air, which confirmed the polarization dependence of third harmonics and the spectral modulation of supercontinuum radiated from filaments. The new phenomenon of spectral modulation is also explored.
