    • Femtosecond laser-induced TiO2 nano structures on titanium 

      Öktem, Bülent; Kalaycıoğlu, Hamit; İlday, F. Ömer (Optical Society of America, 2010)
      We report formation of polarization-dependent nanostructures (nanolines, nanocircles) by high repetition-rate femtosecond laser pulses on titanium surface through a novel mechanism, converting Ti to TiO2. Arbitrarily ...
    • Sub-80 fe dissipative soliton large-mode-area fiber laser 

      Baumgartl, M.; Ortaç, B.; Lecaplain, C.; Hideur, A.; Limpert J.; Tünnermann, A. (2010)
      We report on high-energy ultrashort pulse generation from an all-normal-dispersion large-mode-area fiber laser by exploiting an efficient combination of nonlinear polarization evolution (NPE) and a semiconductor-based ...
