    • Temporal and spectral characterization of near-IR femtosecond optical parametric oscillator pulses 

      Farzam, Parisa (Universitat Politècnica de Catalunya, 2009-09-09)
      Master thesis
      Open Access
      Recently, there has been growing interest in ultrashort pulse measurement techniques. The aim of this work is to utilize interferometric autocorrelator in order to characterize near- IR femtosecond optical parametric ...
    • Transverse cross-correlation scheme for pulse shape measurement in random nonlinear crystals

      We present a novel single-shot cross-correlation scheme based on the measurement of the transverse second harmonic generation (TSHG) in crystals with randomly distributed nonlinear ferroelectric domains. We implement it ...
    • Ultrashort Pulse Characterisation Using an Acousto-Optic Bulk Pulse Shaper 

      Cousin, Seth Lucien (Universitat Politècnica de Catalunya, 2010-06-03)
      Master thesis
      Open Access
      A basic optical setup including an acousto-optic programmable dispersive filter (Dazzler) has been used to fully characterise an ultrashort pulse. A baseband FROG technique has been used to measure the pulse, with pulse ...
