    • High optical efficiency of ZnO nanoparticles 

      Tek, Sümeyra; Demir, Hilmi Volkan; Yucel, D.; Celiker G. (IEEE, 2007)
      We develop optically efficient photocatalytic ZnO nanoparticles that we chemically embed and well disperse into host PVAc thin films and experimentally demonstrate the highest optical efficiency of ∼70% in ZnO nanoparticle ...
    • Spectrally breathing femtosecond pulses from an Er-doped fiber laser 

      Öktem, Bülent; Ülgüdür, Coşkun; İlday, Fatih Ömer (IEEE, 2008)
      We report order-of-magnitude spectral breathing in a dispersion-managed Er-fiber laser with an intracavity bandpass filter. This is to our knowledge the highest of any laser reported. Pulse energy is 1.7 nJ, width is 110 fs.
