Nanosecond laser fabrication of superhydrophobic Ti6Al4V surfaces assisted with different liquids
TL;DR: In this article, the Ti6Al4V surface was textured in air, water, ethanol and saturated sodium bicarbonate solution respectively using a nanosecond pulse fiber laser, and the surfaces with different degrees of hydrophobicity were obtained.

Dual-core antiresonant hollow core fibers
TL;DR: Dual-core antiresonant hollow core fibers (AR-HCFs) are numerically demonstrated, based on knowledge, for the first time, and two fiber structures are proposed, exhibiting low confinement loss and a circular mode profile in each core.

Enhanced 2.75 µm emissions of Er3+ via Eu3+ deactivation in PbF2 crystal
TL;DR: In this paper, the use of Eu3+ codoped for the enhancement of the transition of Er3+: 4I11/2→4I13/2 ~2.75 µm emissions was observed in the Er/Eu co-doped PbF2 crystal for the first time.

Beam shaping and compensation for high-gain Nd:glass amplification
TL;DR: In this paper, the beam shaping and compensation for a high Nd:glass amplification system based on the liquid crystal spatial light modulation technique was reported. And the structure of image transfer was confirmed to be capable of maintaining high-quality image transmission in the amplification process.
