说明:We present a specific-window method to subtract the interference of water vapor on terahertz frequency-domain spectroscopy (THz-FDS) at ambient temperature and pressure. A continuous-wave spectrometer based on photomixing was utilized to obtain THz-F <weixin_38670433> 上传 | 大小:645kb
说明:In this Letter, we study the molecular alignment and orientation driven by two elliptically polarized laser pulses. It is shown that the field-free molecular alignment can be achieved in a three-dimensional (3D) case, while the field-free molecular o <weixin_38750406> 上传 | 大小:681kb
说明:The temporal profiles of high-power short-pulse lasers reflected from self-induced plasma mirrors (PMs) were measured with high temporal resolution in the sub-picosecond window. The leading front shape of the laser pulse is found to depend sensitivel <weixin_38711041> 上传 | 大小:823kb
