ANZUETO-SANCHEZ, G et al. Experimental study of a Q-switched ytterbium-doped double-clad fiber laser. Rev. mex. fis. [online]. 2008, vol.54, n.1, pp.1-4. ISSN 0035-001X.

We report an experimental characterization of a Q-switched operation of an all-fiber laser using ~30m of a double-clad ytterbium-doped fiber spliced to a piece of single-mode un-doped holey fiber. Loss modulation in the splicing point between the active and un-doped fiber due to a substantial coupling of light into lossy cladding modes stimulates pulsed operation of the fiber laser. Pulse energy of ~ 2.5 μJ was estimated and the repetition rate was measured in the range of 4-16 KHz.

Palabras llave : Q-switched; fiber laser; ytterbium-doped fiber.
