  1. 1. Synthesis and optical characterization of optical power limiting platinum(II) acetylides

    Författare :Marcus Carlsson; Bertil Eliasson; Jerker Mårtensson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Platinum acetylides; nonlinear absorption; optical power limiting; Sonogashira coupling; solution gels; thiophene; Organic chemistry; Organisk kemi;

    Sammanfattning : Interactions between light and a molecule can result in reversible or irreversible changes in properties of both the light and the molecule. Of the many known interactions, nonlinear absorption is a process in which an intense light signal, for instance from a laser, can be moderated. LÄS MER

  3. 2. Nonlinear Absorbing platinum(II) Acetylides for Optical Power Limiting Applications

    Författare :Robert Westlund; Eva Malmström; Sergei Vinogradov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical power limiting; Polymer chemistry; Polymerkemi;

    Sammanfattning : During the past few decades, laser technology has had a strong impact on our society, providing important contributions to materials processing, data storage, communications, medicine, and defense applications. However, the progress in laser technology has also brought about the development of harmful portable high‐power lasers and tactical laser weapons. LÄS MER

  4. 3. Dendron decorated chromophores for optical power limiting applications

    Författare :Robert Vestberg; KTH; []
    Nyckelord :Life sciences and physical sciences; polymer chemistry; optics physics; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The need for protection of eyes and electro-optic sensors from powerful lasers has increased the need for new and better optical power limiting (OPL) materials that can protect against laser light. In this study the synthesis and characterization of dendron-coated OPL chromophores (porphyrins, thiophenes, and platinum(II) acetylides) are discussed. LÄS MER
