  1. 1. Concepts for compact solid-state lasers in the visible and UV

    Author : Sandra Johansson; Fredrik Laurell; Patrick Georges; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; nonlinear optics; frequency conversion; visible lasers; ultraviolet lasers; KTiOPO4; BiBO; BBO; quasi phase-matching; birefringent phase-matching; solid-state lasers; Physics; Fysik;

    Abstract : In many fields, scientific or industrial, optical devices that can be tailored in terms of spectral qualities and output power depending on the application in question are attractive. Nonlinear optics in combination with powerful laser sources provide a tool to achieve essentially any wavelength in the electromagnetic spectrum, and the advancement of material technology during the last decade has opened up new possibilities in terms of realising such devices.

  2. 2. Compact diode-pumped solid-state lasers

    Author : Stefan Spiekermann; KTH; []
    Keywords : visible lasers; UV lasers; solid-state lasers;

    Abstract : Compact diode-pumped solid-state lasers (DPSSL) arecontinuously replacing traditional gas lasers as well asenabling completely new technology. However, compact and costefficient designs are required to satisfy end-user demands. Theaim of this thesis was therefore to investigate novel laserdesigns for given applications considering these demands. READ MORE

  3. 3. Characterization of Ultrashort Pulses And Ultrafast Dynamics of Molecules In the Liquid Phase

    Author : Ming Liu; KTH; []
    Keywords : Ultrafast Spectrascopy;

    Abstract : This thesis reports an alternative method for fully acomplete characterization of the UV pump pulse and white lightcontinuum probe pulse, which is commonly used in the pump-probeexperiments to investigate the ultrafast dynamics of molecules.Besides that, real dynamics of infrared cyanine dye molecules(Methyl-DOTCI) and photo-induced dissociation of trihalide ions(I3-or I2Br-) solvated in different organic solvent has alsobeen carefully investigated.
