Electro-optic effects of PbZr0.52Ti0.48O3/PZT) and BaTiO3/BTO) ferroelectric thin films in the terahertz frequency range are studied with high-sensitive ter
We perform a quantum-orbit analysis for the dependence of high-order-harmonic yield on the driving field ellipticity and the polarization properties of the
We investigate experimentally the ionizaiton dynamics of noble gas atoms subject to elliptically polarized intense laser pulses and demonstrate how the ioni
The interference of the harmonic emissions from molecules aligned at different angles can significantly modulate the spectra and result in the anomalous har
We experimentally generated high-order harmonic with minimized angular divergence by using a truncated Bessel (TB) beam which propagates through the optical
We theoretically investigated the generation process of high-order harmonics utilizing the Bohmian trajectories, which are calculated from the accurate nume

科学技术日新月异的今天,多媒体技术辅助教学越来越受到教师的重视.多媒体技术集文本、声音、图形、图像、动画等于一体,创造了一个图文并茂、有声有色、生动逼真的教学情境,
Atomic systems interacting with screened Coulomb potentials are very important in many areas, such as the plasma physics, quantum chemistry and quantum dots
1930年3月2日,中国左翼作家联盟在上海成立.父亲郭沫若是左联49位发起人之一.他当时由于被国民党政府通缉而流亡日本,到1936年左联解散,一直没有回国的可能,所以他和左联的关
