• Watt-level green random laser at 532  nm by SHG of Yb-doped fiber laser 

      Rota Rodrigo, Sergio Upna; Gouhier, B.; Dixneuf, C.; Antoni Micollier, L.; Guiraud, G.; Leandro González, Daniel Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid; Traynor, N.; Santarelli, Giorgio (Optical Society of America, 2018)   Artículo / Artikulua  OpenAccess
      We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ...
    • WDM and TDM interrogation by sequentially pulsing direct modulated DFBs 

      Pérez-González, A.; Bravo Acha, Mikel Upna Orcid; Leandro González, Daniel Upna Orcid; Pérez Herrera, Rosa Ana Upna Orcid; López-Amo Sáinz, Manuel Upna Orcid (Optica, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A new versatile and cost-effective interrogation system by pulsing direct modulated (DM) DFB laser diodes is proposed. 1 pm wavelength resolution and 600 m sensor spacing is demonstrated by sequentially pulsing a DM DFB.
