Polarization dependence of third-harmonics and spectral modulation properties of supercontinuum radiation from plasmas channels generated by femtosecond laser pulses propagation in air
对超短脉冲强激光在大气通道中产生的三次谐波偏振特性及白光光谱调制特性的研究

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.
