High-Harmonic-Repetition-Rate, Extended-Cavity, 1-GHz Tunable Femtosecond Optical Parametric Oscillator Kokabee, Omid Ebrahim-Zadeh, Majid Esteban Martin, Adolfo Àrees temàtiques de la UPC::Enginyeria electrònica::Optoelectrònica::Làser Laser pulses, Ultrashort Synchronously-Pumped Optical Parametric Oscillators (SPOPOs) Nonlinear Optics Nonlinear Frequency Conversion Femtosecond Pulse Generatio GHz Repetition-Rate Impulsos de làser ultracurts Projecte realitzat en col.laboració amb l'Institut de Ciències Fotòniques This 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) with a cavity length longer than the pump cavity length. Near-transform-limited femtosecond pulses at the 14th harmonic of a 76 MHz Kerr-lens mode-locked Ti:sapphire pump laser, corresponding to 1-GHz repetition-rate, and tunable in the telecommunication wavelength region, are generated in a SPOPO based on a 1-mm-thick periodically-poled LiNbO3 (PPLN). A pair of SF11 prisms internal to the SPOPO cavity is used for the dispersion compensation 2009-07-09 Master thesis https://hdl.handle.net/2099.1/7620 eng http://creativecommons.org/licenses/by-nc-nd/3.0/es/ Open Access Attribution-NonCommercial-NoDerivs 3.0 Spain application/pdf Universitat Politècnica de Catalunya
