Fiber design for high-power low-cost Yb:Al-doped fiber laser operating at 980nm [PDF]

, 2007
We investigated an Yb:Al-doped depressed-clad hollow optical fiber (DCHOF) for cladding-pumped 980nm laser operation. With a careful design, the nonzero fundamental-mode cutoff characteristics of a DCHOF allows the competing 1030-1060nm emission to be ...

Strong Linewidth Reduction by Compact Brillouin/Erbium Fiber Laser

IEEE Photonics Journal, 2014
We demonstrate the strong linewidth reduction by a compact Brillouin/erbium fiber laser (BEFL), in which 4-m erbium-doped fiber (EDF) acts as both the Brillouin and linear gain media.

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
