2. 1. Tandem optical parametric oscillators using volume Bragg grating spectral control

   Author : Markus Henriksson; Fredrik Laurell; Hiromasa Ito; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical parametric oscillators; mid-infrared; volume Bragg gratings; PPKTP; ZGP; nonlinear optics; narrowband OPO; Physics; Fysik;

   Abstract : This thesis describes research on near degenerate quasi phase-matched opticalparametric oscillators (OPO) where volume Bragg gratings (VBG) are used toproduce narrow oscillation bandwidth. These OPOs are then used to pump a secondOPO to generate mid-infrared radiation. The atmospheric transmission windows in the 3. READ MORE

4. 2. Nanosecond tandem optical parametric oscillators for mid-infrared generation

   Author : Markus Henriksson; Fredrik Laurell; Gunnar Rustad; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric oscillators; quasi-phase matching; mid-infrared; linewidth narrowing; volume Bragg gratings.; Physics; Fysik;

   Abstract : This thesis discusses a new scheme for generating radiation in the mid infrared spectral region, especially the 3.5-5 µm range. The scheme uses established Nd3+-lasers at 1.06 µm and down conversion in nonlinear optical crystals. READ MORE

5. 3. Enantioseparation of drugs and related compounds using chiral mobile phase additives

   Author : Ngoc Hang Huynh; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

   Abstract : Neutral and anionic chiral mobile phase additives have been employed to separate enantiomers of drugs and related compounds using aqueous buffer solution and hydro-organic solvent mixtures as mobile phases.Ester derivatives of tartaric acid, e. g. READ MORE
