Tunable Single-Longitudinal-Mode High-Power Fiber Laser
International Journal of Optics, 2012 We report a novel CW tunable high-power single-longitudinal-mode fiber laser with a linewidth of ∼9 MHz. A tunable fiber Bragg grating provided wavelength selection over a 10 nm range. An all-fiber Fabry-Perot filter was used to increase the longitudinal

An Injection-Locked Single-Longitudinal-Mode Fiber Ring Laser With Cylindrical Vector Beam Emission [PDF]
IEEE Photonics Journal, 2017 We demonstrate a fiber ring laser with narrow bandwidth single-longitudinal-mode cylindrical vector beam (CVB) output at C-band wavelength range for the first time to the best of our knowledge.

Single-Longitudinal-Mode Dual Wavelength-Switchable Fiber Laser Based on Superposed Fiber Bragg Gratings [PDF]
IEEE Photonics Journal, 2015 In this work, a simple switchable dual-wavelength short-cavity fiber laser operating in a single-longitudinal-mode regime at room temperature and based on superposed fiber Bragg gratings is proposed and experimentally demonstrated.

How to control the laser emission in single longitudinal mode [PDF]
Optica Pura y Aplicada, 2015 Producción Científica In the pictures we show the interference patterns obtained with a solid Fabry-Perot etalon with the 532 nm radiation emitted by a Nd:YAG laser. In Fig. A using a seed laser, this means, only one longitudinal mode. In Fig. B without the seed laser, this is multimode emission.

Single Longitudinal Mode and Widely Tunable Er:Y2O3 Ceramic Laser at ∼ 2.7 μm
IEEE Photonics Journal, 2023 We report on single-longitudinal-mode and tunable operation of an Er:Y2O3 ceramic laser at ∼2.7 μm using intracavity Fabry-Perot etalons combined with a birefringent filter. The laser is pumped with a high brightness, narrow linewidth diode

Non-astigmatic Alexandrite ring laser design with wavelength-tunable single-longitudinal-mode operation [PDF]
, 2020 This work presents a study of a fully nonastigmatic design of a single-longitudinal-mode, wavelength-tunable, unidirectional alexandrite ring laser cavity and assessment of its performance compared to more complex laser design requiring astigmatism ...
