On the initiation of fiber fuse damage in high-power ytterbium-doped fiber lasers
Jiading Tian, Zehui Wang, Qirong Xiao +3
Fiber fuse effect can occur spontaneously and propagate along optical fibers to cause wide-spread damage; it threatens all applications involving optical fibers. This paper present…
Guided mode meta-optics: Metasurface-dressed nanophotonic waveguides for arbitrary designer mode couplers and on-chip OAM emitters with configurable topological charge
Yuan Meng, Tiantian He, Zhoutian Liu +4
Metasurfaces have achieved fruitful results in tailoring complexing light fields in free space. However, a systematic investigation on applying the concept of meta-optics to comple…
High-dimensional classically entangled light from a laser
Yijie Shen, Isaac Nape, Xilin Yang +4
Vectorially structured light has emerged as an enabling tool in many diverse applications, from communication to imaging, exploiting quantum-like correlations courtesy of a non-sep…
Ultrafast two-photon emission in a doped semiconductor thin film
Futai Hu, Liu Li, Yuan Liu +3
As a high-order quantum transition, two-photon emission has an extremely low occurrence rate compared to one-photon emission, thus having been considered a forbidden process. Here,…
Acoustic-optic Q-switched cavityless weak-feedback laser based on Nd:GdVO4 bounce geometry
Rui Guo, Qiang Liu, Mali Gong
An AOQ (acoustic-optic Q-switched) laser with cavityless weak-feedback configuration is demonstrated based on a Nd:GdVO4 bounce geometry. The laser can operate at a repetition up t…
