    • Femtosecond self-doubling optical parametric oscillator based on KTiOAsO4 

      Kartaloğlu, T.; Aytür, O. (IEEE, 2003)
      We report a femtosecond intracavity-frequency-doubled optical parametric oscillator that employs a single KTiOAsO4 crystal for both parametric generation and frequency doubling. This device generates a yellow output beam ...
    • Generation of Sub-20-fs Pulses From a Graphene Mode-Locked Laser 

      Canbaz, F.; Kakenov, N.; Kocabas, C.; Demirbas, U.; Sennaroglu, A. (OSA - The Optical Society, 2017)
      We demonstrate, what is to our knowledge, the shortest pulses directly generated to date from a solid-state laser, mode locked with a graphene saturable absorber (GSA). In the experiments, a low-threshold diode-pumped ...
    • Phase-matched self-doubling optical parametric oscillator 

      Kartaloğlu, Tolga; Köprülü, Kahraman G.; Aytür, Orhan (IEEE, 1996)
      A new self-doubling optical parametric oscillator (OPO) uses a single nonlinear crystal for both parametric generation and frequency doubling. It is based on a KTiOPO4 (KTP) crystal pumped by a Ti:Sapphire laser operating ...
    • 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 ...
    • Sub-picosecond microjoule-class fiber lasers 

      Lecaplain, C.; Ortaç, Bülend; MacHinet G.; Boullet J.; Baumgartl, M.; Schreiber, T.; Cormier, E.; Hideur, A. (Optical Society of America, 2011)
      We study the impact of the mode-locking mechanism on the performances of a microjoule-class all-normal dispersion fiber laser featuring large-mode-area photonic crystal fibers. © 2011 OSA.
    • Ultra-low timing-jitter passively mode-locked fiber lasers for long-distance timing synchronization 

      İlday, F. Ömer; Winter, A.; Kim J.-W.; Chen, J.; Schmüser, P.; Schlarb, H.; Kärtner, F. X. (SPIE, 2006)
      One of the key challenges for the next-generation light sources such as X-FELs is to implement a timing stabilization and distribution system to enable ∼ 10 fs synchronization of the different RF and laser sources distributed ...
