Kilohertz-linewidth and low-threshold single-frequency all-fiber laser utilizing self-developed Nd-doped fluoro-sulfo-phosphate fiber.

Compared to Nd: YAG lasers, Nd-doped fiber lasers offer superior beam quality, compactness, and heat dissipation, especially in generating single-frequency lasers, which holds great promise for applications in optical atomic clocks, quantum computing, and high-precision bio-photonic imaging. In this study, theoretical simulations of the local environment and experimental analyses on the luminescent characteristics of what we believe to be a novel Nd-doped fluoro-sulfo-phosphate (FSP) laser glass were performed to mitigate the concentration and hydroxyl quenching effects. Based on that, a highly Nd-doped (4 mol%) FSP fiber with a large emission cross-section (3.

Characterization of the complete chloroplast genome sequence of (Solanaceae).

is a typical drought and salt-alkali-tolerant plant, which has been added to the new species of in recent years. Here, we first sequenced the complete chloroplast genome of to investigate its evolutionary relationship within the family Solanaceae. Results suggested that the circular complete chloroplast genome of was 154,945 bp in length, including a large single-copy (LSC) of 85,930 bp, a small single-copy (SSC) of 18,203 bp, and two inverted repeats (IRs) of 25,406 bp.

Expanding gain bandwidth using ion-hybridized fiber for kHz-linewidth single-frequency fiber lasers at S-, C-, and L-bands: design and performance evaluation.

Single-frequency fiber lasers at S-, C-, and L-bands play a crucial role in various applications such as optical network expansion, high-precision metrology, coherent lidar, and atomic physics. However, compared to the C-band, the S- and L-bands have wavelength deviations and suffer from excited-state absorption, which limits the output performance. To address this issue, a strategy called ion hybridization has been proposed to increase the differences in site locations of rare earth (RE) ions in the laser matrix, thereby achieving a broader gain bandwidth.

Transcriptional deciphering of the metabolic pathways associated with the bioactive ingredients of wolfberry species with different quality characteristics.

Background: Wolfberry is rich in carotenoids, flavonoids, vitamins, alkaloids, betaines and other bioactive ingredients. For over 2,000 years, wolfberry has been used in China as a medicinal and edible plant resource. Nevertheless, the content of bioactive ingredients varies by cultivars, resulting in uneven quality across wolfberry cultivars and species.

[Comparative analysis of differentially expressed genes for biosynthesis of active ingredients in fruits of different cultivars of L. based on transcriptome sequencing].

To explore the differentially expressed genes (DEGs) related to biosynthesis of active ingredients in wolfberry fruits of different varieties of L. and reveal the molecular mechanism of the differences of active ingredients, we utilized Illumina NovaSeq 6000 high-throughput sequencing technology to conduct transcriptome sequencing on the fruits of 'Ningqi No.1' and 'Ningqi No.

[Clinical experience about manipulative reduction of the radialis and ulnar fractures].

Objective: To observe the clinical efficacy about manipulative reduction of the radialis and ulnar fractures.

Methods: From June 2005 to June 2009, 85 patients with radialis and ulnar fractures, 50 males and 35 females, ranging in age from 1 to 20 years with an average of 10.8 years, were treated with manipulative reduction and external fixation by small splint.
