High-energy all-fiber femtosecond burst laser delivering 158 μJ, 148 fs at 1 kHz repetition rate

Junyu Chen, Haitao Zhang, Xiaozheng Liu, Chenxi Li

We report a high-energy femtosecond chirped pulse amplification burst laser system based on a strictly all-fiber structure. The system consists of a mode-locked fiber oscillator, a pulse stretcher, an acoustic-optic modulator, three fiber amplifiers, and a compressing grating pair. The pulse repetition …

Non-iridescent Structurally Colored Pigments Based on CB@SiO2@TiO2 Core–Bishell Nanospheres with Enhanced Color Stability and Excellent Photocatalytic Activity

Bin Xu, Maohua Hou, Qinqin Xu, Jieying Su et autres

In recent years, artificial amorphous photonic structure (APS) materials with high color saturation and angle independence have been competitively reported. However, there is a lack of research into their functionalization and application in practical environments. Here, with practical applications in mind, we …

Robust Millisecond Coherence Times of Erbium Electron Spins

Shobhit Gupta, Xuntao Wu, Haitao Zhang, Jun Yang et autres

Erbium-doped solids are prime candidates for quantum memories in optical quantum networks given their telecom-compatible photon emission. An electron spin of erbium with millisecond coherence time is desirable for generating remote entanglement between adjacent quantum network nodes. Here we report GHz-range electron-spin …

Carbon‐doped fused silica glass

Haitao Zhang, Aram Rezikyan, Xinyuan Liu, Ling Cai et autres

Abstract Carbon‐doped fused silica glass is fabricated by consolidating zinc stearate‐doped porous silica soot blank. The carbon doping concentration is tunable and a maximum of ~0.3 wt% carbon can be incorporated into densified silica. Carbon dopants assemble into nanorod structures which are …

Subkilohertz optical homogeneous linewidth and dephasing mechanisms in Er3+ : Y2O3 ceramics

Rikuto Fukumori, Yizhong Huang, Jun Yang, Haitao Zhang et autres

Rare-earth dopants in solids are conducive of sharp optical transitions and long spin coherence at cryogenic temperatures. While superb coherences are routine in high-quality bulk crystals, the more versatile materials such as rare-earth doped nanoparticles and ceramics have suffered from excessive decoherence …

La3+ and Er3+ co-doped Y2O3 transparent ceramics with a tunable refractive index and long coherence lifetime

Haitao Zhang, Jun Yang, Jason A. Brown, S. Gray et autres

La3+ is used as an index modifier to tune the refractive index of Er3+ doped Y2O3 transparent ceramics without reducing the coherence lifetime of Er3+ 4I13/2−4I15/2 transition. La3+ and Er3+ are incorporated into Y2O3 through a solution-phase nanoparticle synthesis and nanoparticles are …

Er3+ doped Y2O3 transparent ceramic for quantum memory applications

Jun Yang, Haitao Zhang, S. Gray, Thomas D. Ketcham et autres

We study transparent ceramics made of erbium doped yttria, as a candidate material for quantum storage of photons in the telecom wavelength. Samples with different heat processing conditions are compared. Two different species of Er3+ ions with drastically different dephasing properties are …

Transparent Er3+-Doped Y2O3 Ceramics with Long Optical Coherence Lifetime

Haitao Zhang, Jun Yang, S. Gray, Jason A. Brown et autres

Abstract Er3+-doped Y2O3 nanoparticles (NPs) are used to synthesize transparent ceramics by hot isostatic pressing. Two sizes of NPs are studied, and 40 nm NPs show better performance than 200 nm NPs in transparent ceramics syntheses. The axial optical transmission through millimeter …
