Participation in the absolute gravity comparison with a compact cold atom gravimeter

The first Asia-Pacific Comparison of Absolute Gravimeters (APMP.M.G-K1) was organized by the National Institute of Metrology (NIM) of China from December 21, 2015 to March 25, 2016 in Changping, Beijing. Our compact cold atom gravimeter (CCAG) was transported from Hangzhou to Beijing with a long distance of about 1200 km to participate in this comparison. The CCAG is the only one, to the best of o...
Asymmetric Mathieu beams

We report the generation of asymmetric Mathieu beams: invariant intensity optical profiles that can be described by three parameters. The first one describes the amount of ellipticity, the second one takes into account the degree of asymmetry of the profile, and the third parameter denotes the angular position, where it is localized with the respective asymmetry. We propose a simple angular spectr...
Review of Geostationary Interferometric Infrared Sounder

To measure the global atmospheric three-dimensional distribution and change of temperature and humidity is one of the key areas in atmospheric remote sensing detection; it is also a new research and development direction in the field of meteorological satellite application. As a main element of China second generation of geostationary meteorological satellite Fengyun 4 (FY-4), which was launched o...
Pulse shape of ultrashort intense laser reflected from a plasma mirror

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 sensitively on the laser fluence on the PM surface. Spectral modulation plays a key role in pulse profile shaping. Our findings will extend our knowledge on pro...

Cover Story(Vol.17, Iss.1):Participation in the absolute gravity comparison with a compact cold atom gravimeter [22/01/2019]

High-precision measurementof absolute gravity is very important in Geophysics, Geodesy, Hydrology, Seismology,etc. It is difficult to evaluate the accuracy of an absolute gravimeter (AG) byitself, since the local absolute gravity val...
COL cover story: Asymmetric Mathieu beams [07/01/2019]

Optical lattices are structures oflight generated by interfering optical laser beams, that resemble a crystallattice. This interference creates a standing wave pattern that can be usefulfor the study and applications of light-matter ...
COL cover story: Review of Geostationary Interferometric Infrared Sounder [23/11/2018]

Asa main instrument onboard geostationary meteorological satellite FY-4, geostationaryinterferometric infrared sounder (GIIRS) is used to measure the infraredspectrum of the earth atmosphere. The spectrum is inverted by meteorolo...
COL Cover Story: Pulse shape of ultrashort intense laser reflected from a plasma mirror [10/10/2018]

The interaction of ultrashort intense laser with plasma could produce energetic particles (electrons, positrons, neutrons and ions) and ultrafast radiation sources from microwave to γ-ray. These novel secondary sources have prom...
COL Cover Story: Design of double-zone aspheric diffractive intraocular lens with extended depth of focus [13/09/2018]

The accommodation amplitude of the human eye usually decreases to less than 1 D after 50 years old, resulting in the inability of eyes to focus near object accurately. This dysfunction is called presbyopia, which makes it impossible ...
COL Cover Story: Experimental demonstration of underwater optical wireless power transfer using a laser diode [12/09/2018]

Recently, wireless power charging has attracted considerable attention and has been rapidly deployed in real-life applications. For example, underwater robots working for a long time, it could be efficient to charge the batteries wir...
