    • 83 W, 1 ns, 3.1 MHz all-fiber laser for micromachining 

      Özgören, Kıvanç; Öktem, Bülent; Yılmaz, Sinem; İlday, F. Ömer; Pasin, E.; Eken, K. (IEEE, 2011)
      Fiber lasers are commonly used for various material processing applications. The advantages (such as simplicity of the system, high material removal rate) and disadvantages (larger heat-affected zone, reduced precision) ...
    • 83 W, 3.1 MHz, square-shaped, 1 ns-pulsed all-fiber-integrated laser for micromachining 

      Özgören, Kıvanç; Öktem, Bülent; Yılmaz, Sinem; İlday, F. Ömer; Eken, K. (Optical Society of America, 2011-08-29)
      We demonstrate an all-fiber-integrated laser based on off-the-shelf components producing square-shaped, 1 ns-long pulses at 1.03 mu m wavelength with 3.1 MHz repetition rate and 83 W of average power. The master-oscillator ...
    • Single-mode spectral beam combining of high power Tm-doped fiber lasers with WDM cascades 

      Yılmaz, Sinem; Ottenhues, C.; Theeg, T.; Lamrini, S.; Scholle, K.; Schafer, M.; Fuhrberg, P.; Sayınç, H.; İlday, Fatih Ömer; Neumann, J.; Overmeyer, L.; Kracht, D. (SPIE, 2016)
      Spectral beam combining of Tm-doped fiber lasers can increase the laser output power while simultaneously maintaining the single mode beam quality. We report on a spectral beam combining technique based on highly efficient ...
