An Ultra-narrow-linewidth Microlaser for Nanosensing [PDF]
Conference on Lasers and Electro-Optics 2012, 2012 We report the detection of 11.5-nm radius polystyrene beads in an aqueous environment at a signal-to-noise-ratio of 18:1 by monitoring the split frequency steps of a 5.7-KHz-linewidth microlaser. The thermal-optical effect is also observed.

Multiwatts narrow linewidth fiber Raman amplifiers
Optics Express, 2008 Up to 4.8 W, approximately 10 MHz, 1178 nm laser is obtained by Raman amplification of a distributed feedback diode laser in standard single mode fibers pumped by an 1120 nm Yb fiber laser. More than 10% efficiency and 27 dB amplification is achieved, limited by onset of stimulated Brillouin scattering.

All-Dielectric Color Filter with Ultra-Narrowed Linewidth
Micromachines, 2021 In this paper, a transmissive color filter with an ultra-narrow full width at half of the maximum is proposed. Exploiting a material with a high index of refraction and an extremely low extinction coefficient in the visible range allows the quality factor of the filter to be improved.

Narrow-Linewidth Tin-Vacancy Centers in a Diamond Waveguide [PDF]
ACS Photonics, 2020 Integrating solid-state quantum emitters with photonic circuits is essential for realizing large-scale quantum photonic processors. Negatively charged tin-vacancy (SnV$^-$) centers in diamond have emerged as promising candidates for quantum emitters because of their excellent optical and spin properties including narrow-linewidth emission and long spin
