    • Multiwavelength Raman fiber lasers using Hi-Bi photonic crystal fiber loop mirrors combined with random cavities 

      Rodrigues Pinto, Ana Margarida Upna; Frazão, Orlando; Santos, José Luís; López-Amo Sáinz, Manuel Upna (IEEE / OSA, 2011)   Artículo / Artikulua  OpenAccess
      Different multiwavelength Raman fiber lasers based on a hybrid cavity set-up are proposed. The lasing schemes are based in highly birefringent photonic crystal fiber loop mirrors combined with random cavities. The Hi-Bi ...
    • Narrow-linewidth multi-wavelength random distributed feedback laser 

      Leandro González, Daniel Upna; Rota Rodrigo, Sergio Upna; Ardanaz, Diego; López-Amo Sáinz, Manuel Upna (IEEE / OSA, 2015)   Artículo / Artikulua  OpenAccess
      In this work, narrow-band emission lines are generated by means of two random distributed feedback fiber laser schemes. Spectral line-widths as narrow as 3.2 pm have been measured, which significantly improves previous ...
