    • Quasi-distributed vibration sensing using OFDR and weak reflectors 

      Zhu, Mengshi; Leandro González, Daniel Upna; López-Amo Sáinz, Manuel Upna; Murayama, Hideaki (Optical Society of America, 2019)   Artículo / Artikulua  OpenAccess
      The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ...
    • 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; López-Amo Sáinz, Manuel Upna; Traynor, N.; Santarelli, G. (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 ...
