Coordination Engineering Regulates Emission in Er doped Silicate Glasses and Optical Fibers
The L-band (1565–1625 nm) Er-doped fiber laser light source holds significant application prospects in next-generation optical communications, wind lidar, gas sensing, and quantum communications. 　　The L-band (1565–1625 nm) Er-doped fiber laser light source holds significant application prospects in next-generation optical communications, wind lidar, gas sensing, and quantum communications. However, the development of high-gain Er-doped fibers for the L-band still faces challenges: the emission cross-section (σe) of Er³⁺ ions at wavelengths beyond 1590 nm is relatively low, limiting their gain performance. In existing silica fiber solutions, high phosphorus doping can enhance L-...
Scientists Achieves 3.9 W Single-Frequency Output and Slope Efficiency over 35% in 3 μm Band Fiber Gas Laser
In acetylene lasers operating at 3 μm, the relaxation from the lower laser level to the ground state mainly relies on non-radiative processes such as molecular self-collisions and collisions with the core wall. 　　In acetylene lasers operating at 3 μm, the relaxation from the lower laser level to the ground state mainly relies on non-radiative processes such as molecular self-collisions and collisions with the core wall. The vibrational energy levels v1 and 2v2 of ammonia (NH3) are close to the lower laser level of acetylene and allow radiative relaxation to the ground state. By selecting ammonia as the buffer gas, molecular collisions and energy transfer processes can provide a new relaxation pat...
Researchers Make Progress in Broadband Near-Infrared Fluorescent Glass
Near-infrared (NIR) analysis techniques have increasingly widespread applications in fields such as medical imaging, night vision technology, and non-destructive testing. 　　Near-infrared (NIR) analysis techniques have increasingly widespread applications in fields such as medical imaging, night vision technology, and non-destructive testing. However, existing NIR materials still face limitations in luminescence efficiency and spectral range, particularly in applications requiring broadband NIR emission. Traditional NIR materials typically rely on rare-earth elements, which are not only costly but also limited in resources. Therefore, the development of novel...
Researchers Make Progress in Developing Novel Transparent Glass Ceramics Exhibiting Narrowband Emission from Eu²⁺
Rare earth ions are essential in laser materials and lighting technology for their intricate energy level structures and excellent optical properties 　　Rare earth ions are essential in laser materials and lighting technology for their intricate energy level structures and excellent optical properties. However, the rare earth ions capable of laser output are mainly trivalent (such as Nd³⁺, Yb³⁺, etc.), and their laser output wavelengths are primarily in the infrared region. In contrast, although Eu²⁺ ions exhibit excellent luminescence efficiency in the 5d→4f transition, they struggle to achieve laser output due to the strong absor...
Researchers Make Progress in Expanding the Bismuth NIR Emission Band in Bi-doped Silica Glass and Fiber
With the exponential growth of data-driven technologies like artificial intelligence and cloud computing, the demand for ultra-wideband optical communication systems has surged. 　　With the exponential growth of data-driven technologies like artificial intelligence and cloud computing, the demand for ultra-wideband optical communication systems has surged. Current erbium-doped fibers, limited by their narrow amplification bandwidth (C-band: 1530-1565 nm), struggle to meet these escalating needs. Bismuth (Bi)-doped fibers, known for the broad near-infrared (NIR) emission bands (1350-1500 nm and 1600-1800 nm), have emerged as a promising alternative. However, the low ...
