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

    Författare :Ming Liu; KTH; []
    Nyckelord :Ultrafast Spectrascopy;

    Sammanfattning : 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.

  3. 7. High Power, Long Wavelength Semiconductor Disk Lasers for Continuous and Mode-Locked Operation

    Författare :Hans Lindberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mode-locking; thermal management; spectral properties; optically pumped; single frequency; beam quality; vertical-external-cavity surface-emitting laser; disk laser; Semiconductor laser;

    Sammanfattning : The semiconductor disk laser has recentlyemerged as an attractive alternative to bulky and power consuming gas and solid state lasers. It offers compact, powerful and efficient devices with W level output power and beam properties earlier not achieved with semiconductor lasers. LÄS MER

  4. 8. Coherent Multidimensional Spectroscopy as a Probe of System-Bath Interactions

    Författare :Niklas Christensson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Spectroscopy Photon Echoes System-Bath Interactions Carotenoids;

    Sammanfattning : The interaction of molecules with their environment has a profound effect on dynamics in molecular systems. System-bath interactions, or the interaction of electronic and nuclear degrees of freedom, are important in order to understand chemical reactions and transport of energy and electrons in the condensed phase.
