Visible fiber lasers are attracting increasing research attention due to their potential applications in biophotonics, display systems, laser processing, etc. [1]. Among available glass hosts, silica offers unmatched mechanical robustness, chemical durability, and technological maturity, making it particularly attractive for deployment outside the laboratory. Despite these advantages, visible...

Pulsed gallium nitride (GaN) semiconductor lasers offer a compact, robust, and cost-effective source for underwater LiDAR (Light detection and ranging), with applications in object detection, property measurement, optical sensing, environmental monitoring, and defence [1,2]. Practical deployment, however, requires sufficient pulse energies to overcome absorption and scattering, especially when...

Contributed Oral

Diamond particles containing nitrogen-vacancy (NV) centers enable fiber-based magnetic field sensing by allowing optical excitation and collection of NV fluorescence within an optical fiber. Tellurite glass is a promising host for NV-diamond particles because its refractive index (~2.0) is closer to that of diamond (~2.4) than most oxide and fluoride glasses, thereby reducing scattering at the...

Contributed Oral

Wavelength modulation spectroscopy (WMS), employing a 1654-nm tunable diode laser and an annular polygon-reflector multi-pass optical cell, has been developed to study enteric emissions of methane (a key greenhouse gas) from ruminant livestock. This molecule-specific technique can quantitatively measure sub-parts-per-million concentrations of methane in ambient air at atmospheric pressure. A...
