Phase dependence of third-order harmonic generation in gases induced by two-color laser field
《Chinese Optics Letters》2023年第5期1-5,共5页孟从森 宋盼 吕治辉 王小伟 张栋文 赵增秀 袁建民 
supported by the National Key Research and Development Program of China(No.2019YFA0307704);the National Natural Science Foundation of China(Nos.11974425 and 11974426);the National Safety Academic Fund(No.U1830206)。
We experimentally demonstrate third-harmonic generation(THG)in gases ionized by a femtosecond laser pulse superimposed on its second-harmonic(SH).The mechanism of THG has been investigated,and it demonstrates that a t...
