   Abstract : Abstract In this thesis, the high temperature superconductors (HTSC) La2CuO4+x and Bi2Sr2CaCu2O8+d and the colossal magnetoresistive (CMR) La1-xSrxMnO3 have been studied by photoelectron spectroscopy. Techniques such as angular resolved photoemission (ARPES), resonant photoemission spectroscopy (RESPES) and x-ray absorption spectroscopy have been applied, using synchrotron radiation. READ MORE

6. 4. Multi-Photon Interactions with a Time Structure

   Author : Alexander Baev; KTH; []
   Keywords : nonlinear optics; two-photon absorption; mirrorless lasing; charge-transfer chromophores; solutions; resonant photoemission; life-time vibrational interference; scattering duration time; electron Doppler effect; polymers;

   Abstract : The present thesis concerns aspects of the interaction ofmatter in gas, liquid and solid phases, with electromagneticradiation, ranging from the optical to the X-ray region. Overthe last decade the availability of ultrashort strong laserpulses as well as of high power synchrotron sources of tunableX-ray radiation has stimulated a rapid development of newexperimental techniques which makes it possible to analysedifferent physical, chemical and biological processes inunprecedented detail.
