摘要
研究了超短脉冲强激光在大气中传输产生电离通道后辐射的三次谐波强度随激光偏振的变化.此外,还研究了产生的白光辐射在短波长上的有规律的谱调制,分析了白光谱调制的产生机理.
We carried out spectroscopic studies on the supcrcontinuum 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.
