AI Contributes to Ocean Eddy Detection by Synthetic Aperture Radar

Scientists at the Aerospace Information Research Institute (AIR) under the Chinese Academy of Sciences (CAS), in collaboration with their international collogues, have proposed a state-of-the-art deep-learning network, named EOLO, aiming to improve the detection of ocean eddies observed in C-band spaceborne synthetic aperture radar (SAR) imagery. This work has been published in Remote Sensing of Environment , which combines advanced AI algorithms with high-resolution spaceborne SAR data, providing a methodological basis for further studies of sub-mesoscale eddies.

Old Crystal, New Story for Enhancing Deep Ultraviolet Laser Performance

A recent breakthrough from researchers at the Chinese Academy of Sciences propels this field forward. As reported in Advanced Photonics Nexus, they achieved a remarkable 60-milliwatt (mW) solid-state DUV laser at 193 nm with a narrow linewidth using a sophisticated two-stage sum frequency generation process employing LBO crystals. The process involves pump lasers at 258 and 1553 nm, derived from a Yb-hybrid laser and an Er-doped fiber laser, respectively. This setup, culminating in a 2mm×2mm×30mm Yb:YAG bulk crystal for power scaling, demonstrates impressive results.
