In this work, a fiber ring laser sensor has been employed to analyze the influence of passive Er-doped fiber acting as saturable absorber. Lasing modes of fiber ring lasers can be reduced by properly locating a saturable ...

We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber and that ...

We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis (BOTDA) sensor that is able to operate with a probe power larger than the Brillouin threshold of the deployed sensing fiber ...

Virtual FBGs using saturable absorbers for sensing with fiber lasers

Rodríguez Cobo, Luis; Pérez Herrera, Rosa Ana

; Quintela, M. A.; Ruiz Lombera, Rubén; López-Amo Sáinz, Manuel

; López Higuera, José Miguel (MDPI, 2018) Artículo / Artikulua

The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
