Elementary tellurium is attracting increasing attention due to its unconventional properties with three two-dimensional phases and the existence of Weyl nodes around its Femi level. Unlike chemically synthesized tellurium crystals (Chem-Te) which ...2019-09-05
Among laser materials, Nd,Y-codoped Ca1-xSrxF2 is considered an ideal host material for rare-earth ions because of their low phonon energy, small nonlinear refractive index, wide transparency range, and high thermal conductivity. However, the tran...2019-09-12
Synthetic fused silica has been widely used as an optical fiber material for its high transparency in the visible and near-IR spectral range as well as its mechanical robustness, high chemical resistance and good biomedical compatibility. Unfortun...2019-09-11
Yb3+/Al3+/P5+ co-doped silica fibers have attracted considerable attention in high-power fiber laser. However, the fiber preform undergoes a series of thermal procedures during the drawing process, leading to significant changes in the network str...2019-09-11
Owing to wide applications in numerous interesting laser–matter interaction phenomena in the relativistic or ultra-relativistic region, many petawatt (PW) laser facilities have been demonstrated around the world in the past decade. 2019-09-10
A wide use of fluorozirconate glass fiber has aroused significant interests for its operation in defense, medical, processing, scientific research, and mid‐infrared amplifiers. However, the attenuation of fluoride glass fiber is much higher than ...2019-09-09
Free of some degree of crystallinity, single-component Al2O3 atomic-level glass cannot be obtained by conventional melt quenching methodology. This is because extremely high quenching rates are needed to achieve an amorphous state for glass interm...2019-09-09
Up to now, the output of high-power femtosecond laser facilities has grown from several terawatts (TWs) to 10 PW, which enables the creation of an ultra-intense laser field with the intensity up to 1022 W/cm2 at the focus. Such extreme conditions ...2019-09-04
Liquid crystal phased devices (LCPDs), with the advantages of high spatial resolution, compact structure and low power, can realize precise control of the beam amplitude, wavefront, polarization and steering. They have wide applications in laser f...2019-09-02
It has shown that computational imaging (CI) enjoys the rapid development of artificial intelligence, especially deep learning. However, existing learning-based CI methods usually need to experimentally collect a large number of input-output data ...2019-08-29
