Tunable Single-Longitudinal-Mode High-Power Fiber Laser [PDF]

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

Diode-Pumped Single-Longitudinal-Mode Pr³⁺:YLF Laser Based on Combined Fabry–Perot Etalons at 522.67 nm

Photonics, 2023
We create a rate equation theoretical model of a continuous-wave end-pumped Pr3+:YLF SLM laser that characterizes the output properties of a single-longitudinal-mode (SLM) green laser. After inserting two Fabry–Perot (F–P) etalons with thicknesses of 0.3
