High-power fiber lasers: new developments [PDF]
SPIE Proceedings, 2003 We assess different power limits of cladding-pumped fiber lasers. Despite recent advances in pump sources, these are still primarily limited by available pump power. We find that it should be possible to reach output powers beyond 1 kW in single-mode ytterbium doped fiber lasers.

Astronomical Applications of Multi-Core Fiber Technology [PDF]
, 2020 Optical fibers have altered astronomical instrument design by allowing for a complex, often large instrument to be mounted in a remote and stable location with respect to the telescope.

Frontiers in Plant Science, 2021 As two cultivated widely allotetraploid cotton species, although Gossypium hirsutum and Gossypium barbadense evolved from the same ancestor, they differ in fiber quality; the molecular mechanism of that difference should be deeply studied.

Fiber Optic Sensors: Recent Developments
Analytical Letters, 1990 Abstract Biosensors are attracting the attention of many investigators in the field of biotechnology related research. A biosensor is a device that combines the specificity of a biomaterial (enzymes, antibodies, receptors or even whole cells) with sensitive, well established bioassays.

Study of quasi-distributed optical fiber methane sensors based on laser absorption spectrometry [PDF]
, 2019 The coal industry plays an important role in the economic development of China. With the increase of coal mining year by year, coal mine accidents caused by gas explosion also occur frequently, which poses a serious threat to the life safety of ...

Dual functions of Expansin in cell wall extension and compression during cotton fiber development
Biologia, 2020 Cotton fiber provides a distinct picture of cell wall synthesis. It is an epidermal single-cell extension of Cotton plant seed and undergoes three main stages of development, (1) initiation, (2) elongation and (3) maturation.

The Fiber Walk: A Model of Tip-Driven Growth with Lateral Expansion [PDF]
, 2013 Tip-driven growth processes underlie the development of many plants. To date, tip-driven growth processes have been modelled as an elongating path or series of segments without taking into account lateral expansion during elongation.

Developing Lignosulfonate-Based Activated Carbon Fibers [PDF]
Materials, 2018 In this study, electrospinning technology, physical activation, and carbonization processing were applied to produce lignosulfonate-based activated carbon fibers. The porous structure of the produced lignosulfonate-based activated carbon fibers primarily contained mesopores and a relatively small amount of micropores.
