Journal ArticleDOI
Self-calibration and laser energy monitor validations for a double-pulsed 2-μm CO 2 integrated path differential absorption lidar application.
TL;DR: Self-calibration feature of the 2-μm IPDA lidar allows one to monitor the transmitted laser energy, through residual scattering, with a single detection channel, which reduces the CO2 measurement uncertainty.
Journal ArticleDOI
Field testing of a high-energy 2-μm Doppler lidar
Grady J. Koch,Jeffrey Y. Beyon,Paul E. Petzar,Mulugeta Petros,Jirong Yu,Bo C. Trieu,Michael J. Kavaya,Upendra N. Singh,Edward A. Modlin,Bruce W. Barnes,Belay Demoz +10 more
TL;DR: In this article, a 2-µm wavelength coherent Doppler lidar for wind measurement has been developed of an unprecedented laser pulse energy of 250mJ in a rugged package.
Proceedings ArticleDOI
Single frequency fiber laser at 2.05 μm based on Ho-doped germanate glass fiber
TL;DR: In this article, a single frequency fiber laser operating near 2 micron with over 50 mW output power has been demonstrated by using a short piece of newly developed single mode holmium-doped germanate glass fiber.
Journal ArticleDOI
Gut Microbiota Interact With the Brain Through Systemic Chronic Inflammation: Implications on Neuroinflammation, Neurodegeneration, and Aging
Yi Mou,Yu-zheng Du,Lixing Zhou,Jirong Yu,Xian-Liang Hu,Yixin Liu,Sao Chen,Xiufang Lin,Gongchang Zhang,Hengyi Xiao,Birong Dong +10 more
TL;DR: To add depth to the bridging role of systemic chronic inflammation, a plausible mechanism indispensable for BBB corruption was highlighted; namely, BBB maintenance cues are affected by inflammatory cytokines, which may help to understand how GM and its metabolites play a major role in NF&ND and aging.
Journal ArticleDOI
An Airborne 2-μm Double-Pulsed Direct-Detection Lidar Instrument for Atmospheric CO2 Column Measurements
Jirong Yu,Mulugeta Petros,Upendra N. Singh,Tamer F. Refaat,Karl Reithmaier,Ruben Remus,William Johnson +6 more
TL;DR: In this article, a 2-μm double-pulsed integrated path differential absorption (IPDA) lidar was used to measure CO2 column density with unique features.
