Abstract: In this paper, we present a single-longitudinal mode (SLM) Ytterbium-doped fiber laser (YDFL) featuring a six-subring cavity (SSRC) structure. The YDFL achieves SLM output through use of the ...
John Baez, Joe Moeller and Todd Trimble, 2-rig extensions and the splitting principle. Our paper categorifies a famous method for studying vector bundles, called the ‘splitting principle’. But it also ...
Abstract: In this paper, we demonstrate a stable output single-longitudinal-mode (SLM) Erbium-doped fiber laser (EDFL) with eight selectable wavelengths. The EDFL achieves wavelength selection through ...
A single-longitudinal-mode (SLM) thulium-doped fiber laser, based on an eye-shaped passive dual-ring filter, is designed and constructed. The eye-shaped passive compound cavity consisting of four ...
Thulium-doped fiber laser with switchable single-wavelength output using polarization-dependent loss
A thulium-doped fiber laser (TDFL) with switchable single-wavelength output was proposed and experimentally constructed, and its output characteristics were investigated. The central wavelengths were ...
Physicists have discovered that the ring of photons orbiting a black hole exhibits a special kind of symmetry, hinting at a deeper meaning. When photons hurtle toward a black hole, most are sucked ...
Mathematics is the universal language of science and a beautiful subject in its own right. It is a discipline that also has important applications in industry and commerce, and well-qualified ...
This degree combines the best aspects of the separate mathematics and physics degrees, offering enhanced flexibility, increased choice and the opportunity to pursue some of the most interesting and ...
Rings around a black hole: illustration showing the n=0,1 and 2 rings. (Courtesy: George Wong (UIUC) and Michael Johnson (CfA)) Adding a space telescope to the earthbound Event Horizon Telescope (EHT) ...
