1. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. READ MORE

5. Evaluation of white-light generation as possible seed for a mid-infrared optical parametric chirped pulse amplifier
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/KärnfysikAbstract : White-light spectra of different crystals, based on 1030-nm intense pump pulses have been investigated in order to derive a near-infrared seed for mid-infrared generation. Among ten crystals, YAG (yttrium aluminium garnet), KGW (potassium gadolinium tungstate) and YVO4 (yttrium orthovanadate) exhibit the most suitable properties for supercontinuum generation with high efficiency for spectral broadening as well as high tolerance to optical damage.
