Effects of microbe-derived antioxidants on growth, digestive and aminotransferase activities, and antioxidant capacities in the hepatopancreas of Eriocheir sinensis under ammonia nitrogen stress Open
This study evaluated the effects of feeding a microbial-derived antioxidant diet (MA) for 56 days on the growth performance of Eriocheir sinensis, as well as on digestive and metabolic enzyme activity and antioxidant capacity under ammonia…

Generation of Terawatt-Scale Vortex Pulses Based on Optical Parametric Chirped-Pulse Amplification Open
In this letter, we report the demonstration of terawatt (TW)-scale femtosecond vortex laser pulses based on noncollinear optical parametric chirped-pulse amplification (OPCPA) centered at 800 nm. To the best of our knowledge, this is the f…

Generation of High-Purity Laguerre–Gaussian Beams by Spatial Filtering Open
We theoretically and experimentally demonstrate that high-purity Laguerre–Gaussian beams can be efficiently obtained from Gaussian vortex beams using a typical 4F spatial filtering optical system, in which spatial filtering does not affect…

Formation of in-volume nanogratings with sub-100-nm periods in glass by femtosecond laser irradiation Open
We present direct experimental observation of the morphological evolution during the formation of nanogratings with sub-100-nm periods with the increasing number of pulses. Theoretical simulation shows that the constructive interference of…
