We studied the ionization and dissociation of polyatomic molecule methane in an intense femtosecond laser field with wav......

A novel method for accurately measuring chromatic dispersion of optical fibers is proposed based on the use of chirped i......

The nonparaxial property of the chirped pulsed beam is analyzed both quantitatively and qualitatively. Through the quali......

The behavior of population transfer in an excited-doublet four-level system driven by linear polarized few-cycle ultrash......

The spectral resolved femtosecond pump-probe experiment is applied to measure the third order nonlinear refractive index......

研究了飞秒激光成丝过程中钳制光强对脉宽的依赖关系。对不同脉宽成丝钳制光强进行直接实验测量,发现当脉宽逐渐展宽(由45 fs展宽......
