  2. 2. Partially Coherent Laser Radiation - Modeling and Application to Optical Microlithography

    Author : Christer Rydberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microlithography; coherence; temporal speckle; partial coherence; optical propagation; number of degrees of freedom; dynamic speckle;

    Abstract : This work deals with a type of light that has properties somewhere between blackbody radiation and conventional laser light; such light is referred to as partially coherent. One example is the radiation from the pulsed excimer laser, which is used in the manufacturing of most of the worlds integrated circuits. READ MORE

  3. 3. Statistical optics and optical elements for microtechnologies: Partial coherence, lithography and microlenses

    Author : Christer Rydberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse methods; microlenses; optical propagation; partial coherence; dynamic speckle; lithography;

    Abstract : The scientific problems treated in this thesis are expressed within the framework ofstatistical optics and are generated out of the optical lithography industry. Opticallithography uses partially coherent light, i.e. light with a random wavefront, toincrease the performance of the lithographic process. READ MORE

  4. 4. A Triple Helix of Learning Processes - How to cultivate learning, communication and collaboration among distance-education learners

    Author : Eva Rydberg Fåhraeus; KTH; []
    Keywords : Distance education; collaborative learning; Computer-supported collaborative learning; CSCL; information and communication technology; ICT; forum system; learning processes;

    Abstract : This work focuses on collaborative learning and how it canbe applied and supported in distance education. Previous workindi-cates that distance learners experience more loneliness,technical problems and lack of stimulation than face-to-facelearners do. Collaboration with peers may improve the feelingof connectedness and engagement. READ MORE

  5. 5. Synchrotron radiation induced fluorescence spectroscopy of gas phase molecules

    Author : Jesús Álvarez Ruiz; Elisabeth Rachlew; J. E. Rubensson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; molecular spectroscopy; photon induced fluorescence; synchrotron radiation; superexcited states; Fysik; Physics; Fysik;

    Abstract : A new experimental set-up for gas phase fluorescence studies using synchrotron radiation has been designed and constructed to perform simultaneously total and dispersed fluorescence measurements. Neutral photodissociation of CO has been investigated after excitation with 19-26 eV photons. READ MORE
