The global GHGs (carbon dioxide and methane) levels are critical for studying the global carbon cycle. Space-borne integrated-path differential absorption (IPDA) LIDAR systems can measure carbon dioxide column concentration globally with 1 ppm acc...2019-11-11
Recently, based on a self-developed high-power yellow laser and gated photon counting technique, the research group from Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences (CAS) demonstrated a remote-magnetometry sc...2019-11-08
Cooperite or platinum sulfide (PtS) is a rare mineral with nonlayered structure. Its general existence in small size and irregular shape with inevasible impurities either in natural or artificial synthetic type has hindered the study of its intrin...2019-11-06
With the development of the next generation of synchrotron radiation and free electron lasers, x-ray measurement and imaging, such as x-ray holography and biochemical microscopy, has become a hot spot again. In many x-ray imaging methods, holograp...2019-10-31
Spatio-temporal couplings (STCs) play a vital role in the transport and compression of an ultrashort pulsed beam. Although STCs can be useful in optimizing nonlinear processes and generating an attosecond pulse, those couplings can lead to a stron...2019-10-28
Mid-IR laser plays a significant role in ultrafast spectroscopy and strong-field experiments and have continuously attracted a great deal of interest, both scientifically and technologically. In this scenario, the accurate characterization of ultr...2019-10-25
Perovskite quantum dots have great potential application in photoelectric device due to the excellent optical properties, such as narrow-band luminescence, good monochromaticity, and high photoluminescence quantum yield. However, the problems of i...2019-10-11
Semiconductor nanolaser, with high spectral purity and stability, namely single-mode nanolaser, is very desirable in color laser display, on-chip optical communication and computing. To date, most of reported nanolasers just exhibit multimode stru...2019-10-11
Leading to the yellow region visible lasers, the continuous development of laser medicine, biomedical instruments and telecommunication have drawn much attention in past few years. Regrettably, there is still a blank region in this band for laser ...2019-10-11
The process of two beams superposition is a knotty problem for scholars of different research fields like stimulated emission depletion microscopy (STED). The mainstream channel of two or more laser beams superposition is mutually aligned by using...2019-10-08
