High-Harmonic-Repetition-Rate, Extended-Cavity, 1-GHz Tunable Femtosecond Optical Parametric Oscillator (Universitat Politècnica de Catalunya, 2009-07-09)
Open AccessThis work is devoted to the experimental demonstration of a novel concept for the generation of femtosecond pulses at the harmonics of the pump repetition rate in a synchronously-pumped optical parametric oscillator (SPOPO) ...
Temporal and spectral characterization of near-IR femtosecond optical parametric oscillator pulses (Universitat Politècnica de Catalunya, 2009-09-09)
Open AccessRecently, 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 ...
Open AccessA two-dimensional theoretical model for the field generated in the thermoelastic regime by line-focused laser illumination of a homogeneous, isotropic, linearly elastic half-space is presented. The model accounts for the ...
(Universitat Politècnica de Catalunya, 2010-06-03)
Open AccessA 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 ...
