Examining the Chemical and Optical Properties of Biomass-burning Aerosols and their Impact on Oxidative Potential

Aerosol and Air Quality Research, 2023
The use of biomass fuels for cooking persists on a large scale in rural areas of many low-and middle-income countries, including India. Exposure to emissions from biomass cooking is linked with adverse respiratory health outcomes - likely mediated ...

By Making Me Stink to the Inhabitants of the Land: Intrusive Smells as a Metaphor for Unwanted Migrants [PDF]

, 2022
The verb ba’ash (lit. “to stink”) is used repeatedly in the Hebrew Bible to describe unwanted groups or individuals (Gen 34:30; Exod 5:21; 1 Sam 13:4; 1 Sam 27:12; 2 Sam 10:6; 1 Chr 19:6).

A 5 kW Nearly-Single-Mode Monolithic Fiber Laser Emitting at ~1050 nm Employing Asymmetric Bi-Tapered Ytterbium-Doped Fiber

Photonics, 2023
Limited by stimulated Raman scattering (SRS), amplified spontaneous emission (ASE) and transverse mode instability (TMI), it is challenging to achieve high-power laser output in ytterbium-doped fiber (YDF) lasers with operating wavelengths less than 1060

Seeding High Brightness Fiber Amplifiers With Multi-Phase Coded Signal Modulation for SBS Effect Management

IEEE Access, 2020
We propose a new modulation approach based on multi-phase coded signal (MPCS) to increase stimulated Brillouin scattering (SBS) threshold in high power narrow-linewidth fiber amplifiers.

High Power Linearly Polarized Raman Fiber Laser With Stable Temporal Output

Photonic Sensors, 2018
We demonstrate a high power linearly polarized Raman fiber laser (RFL) pumped by an amplified spontaneous emission (ASE) source. Temporal-stable operation of RFL could be ensured owing to the employment of ASE, which mitigates the inherent intensity ...

Demonstration of 3 kW-Level Nearly Single Mode Monolithic Fiber Amplifier Emitting at 1050 Nm Employing Tapered Yb-Doped Fiber

IEEE Photonics Journal, 2023
Tapered Yb-doped fiber (T-YDF) can balance the suppression of transverse mode instability (TMI) and stimulated Raman scattering (SRS) in high power fiber lasers.
