1. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processesMaster-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen
Sammanfattning : 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. LÄS MER

Sammanfattning : During this thesis, work has been done towards realizing a short-wave infrared (SWIR) laser source based on optical parametric amplification. It is planned that this setup should be able to produce few-cycle laser pulses at 2μm with a stable carrier-envelope phase (CEP). LÄS MER
3. Evaluation of white-light generation as possible seed for a mid-infrared optical parametric chirped pulse amplifierMaster-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik
Sammanfattning : 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.
