1. 1. Optical Characterization of Lignin Nanoparticles

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Kristoffer Linder; [2020]
   Keywords : lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

   Abstract : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. READ MORE

3. 2. Dispersion management and characterization of ultrashort laser pulses for the optimization of parametric processes

   Author : Axel Elfving; [2019]
   Keywords : frequency resolved optical gating; optical parametric amplification; difference frequency generation; nonlinear optics; laser pulse compression; lasers; optics; Technology and Engineering; Physics and Astronomy;

   Abstract : 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

4. 3. Noncollinear optical parametric amplification of a supercontinuum

   Abstract : A confocal microscope is built to examine molecular powders, and in particular the (PhSn)_4S_6 cluster, that emits white light when irradiated with infrared laser light. The confocal microscope operating at long working distances is assembled and characterized. READ MORE

6. 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/Kärnfysik

   Author : Chuang Lu; [2017]
   Keywords : nonlinear linear optics; ultrafast optics; Mid-infrared generation; near-infrared; Optical parametric amplification; Optical Parametric Chirped-pulse Amplification; supercontinuum generation; white-light generation; laser induced filamentation; Dispersion-scan; nonlinear propagation; Physics and Astronomy;

   Abstract : 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.
