A theoretical study for femtosecond laser-induced ultrafast electro-absorption of bulk solids is presented. Our nu-merical results show that, in the case of low
A compact all-fiber polarization-maintaining Er:laser using a nonlinear amplifying loop mirror is reported.Fundamental single-pulse mode-locking operation can a
To reveal the energy transmission through a hybrid phononic crystal structure,power flow analysis is carried out in this paper.Hysteretic damping having signifi
Based on ab initio calculations,it is found that the donor center of substitutional sulfur (S) in diamond with C2v symmetry is more stable than that with C3v sy
The real time domain interferometry for the photodetachment dynamics driven by the oscillating electric field has been studied for the first time.Both the geome
We theoretically study the optical nonreciprocity in a piezo-optomechanical microdisk resonator,in which the cavity modes and the mechanical mode are optically
A parametric study of the clustering transition of a vibration-driven granular gas system is performed by simulation.The parameters studied include the global v
