    In September of 1979 the IBM Journal of Research and Development published a special issue in which we described some of IBM's contributions to basic laser science and technology over the twenty-year period following invention of the laser in 1960. That involvement has included the invention of new lasers, the development of novel techniques for extending the usable range of wavelengths, and impor... View full abstract»

    We have developed experimental electroplating, electrodeless plating, and etching techniques that use a focused laser beam to define the localized plating or etching region. Enhancements in plating (etching) rates up to ≈103 to 104, compared to background rates, have been observed in the region of laser irradiation. A thermal model has been developed to describe the ob... View full abstract»

    The laser-enhanced chemical etching of Si, SiO2, Ta, and Te films with halogen-containing gases excited by a pulsed CO2 laser and a continuous-wave (cw) Ar+ laser has been studied. Detailed measurements of the etch rates as functions of the laser frequency, the laser intensity, and the gas pressure have been performed for some of the gas-solid systems. The enhanced...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (736 KB)

    A new technique for speckle-free, fine-line high-speed lithography using high-power pulsed excimer lasers is described and demonstrated. Use of stimulated Raman shifting is proposed for obtaining the most desirable set of spectral lines for any resist. This permits, for the first time, the optimization of the exposure wavelengths for a given resist, rather than the reverse situation. Excellent-qua... View full abstract»

  • Image Projection with Nonlinear Optics

    Publication Year: 1982, Page(s):160 - 170
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (996 KB)

    The nonlinear optical process of conjugate wavefront generation by degenerate four-wave mixing can project images in a manner akin to conventional optical systems. The underlying physics is quite different, and the difference allows higher resolution over larger useful fields. This article reviews the basics of conjugate wavefront generation and its relationship to holography, and proposes applica... View full abstract»

    The paper discusses an emerging area of laser-semiconductor processing: the effect of laser irradiation on the electrical parameters of diffused-junction devices. Shallow diffusions of 0.2- to 0.5-µm depths have been achieved. Transistor current gains have been modified and the results agree with the theoretical analysis. View full abstract»

  • The Application of GaAlAs Lasers to High-Resolution Liquid-Crystal Projection Displays

    Publication Year: 1982, Page(s):177 - 185
    Cited by:  Patents (11)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (840 KB)

    In this review we describe a high-resolution liquid-crystal (LC) display that uses multiple GaAlAs lasers to write on the LC cell. Arrays of high-powered lasers were needed to meet the writing speed requirements of the display. A fiber optic delivery system was developed to allow high-resolution, multi-spot writing on the cell, regardless of the laser configuration used. The flexibility and uncons... View full abstract»

  • Lasers in Electrophotography

    Cited by:  Patents (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (945 KB)

    We review the recent advances in the use of laser sources in the field of electrophotography. New experimental investigations of the photogeneration and transport processes utilized in electrophotography are now possible because of the short pulse duration, high peak power, high collimation, monochromaticity, and/or coherence of a laser source. Also, the increasing availability of reliable and ine... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (910 KB)

    A scheme for optical information storage using photochemical hole burning (PHB) in amorphous systems is evaluated. Limits imposed by the nature of PHB in polymers and glasses and its dependence on temperature are discussed. It is demonstrated that optical information storage can be multiplexed by a factor of 103 using the frequency dimension and PHB. View full abstract»

  • Integrated Optics and Raman Scattering: Molecular Orientation in Thin Polymer Films and Langmuir-Blodgett Monolayers

    Cited by:  Patents (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (622 KB)

    Studies of submicron films and molecular monolayers with infrared and Raman spectroscopy have been hampered by the inability of current spectroscopic techniques to detect the minute amount of material present in these thin-film assemblies. A method for overcoming this problem by using integrated optics has been successfully demonstrated. In the case of Raman studies, the material whose spectrum wa... View full abstract»

  • A New Class of Materials for Holography in the Infrared

    Publication Year: 1982, Page(s):217 - 227
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (832 KB)

    A new class of holographic materials is described. These materials undergo four-level two-photon photochemistry. The holograms recorded in these materials are self-developing and are not erased during reading. Furthermore, the recording process may be gated off and on by using an auxiliary incoherent light source. As a specific example of such a system, holograms formed using samples of an α...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (572 KB)

    The IBM 3687 Supermarket Scanner is described, with emphasis on the holographic deflector disk used to create the scan pattern. The scanner exploits the functional advantages of holography to create a dense, multiple-focal-plane scan pattern with small spot size and large depth of field. The optical design of the holographic disk is discussed and basic disk fabrication concepts are introduced. View full abstract»

    Laser-induced arcing in cathode ray tubes has been used to study the effect of spontaneous internal high-voltage arcs under normal operating conditions. Ruby and Nd:YAG laser systems were compared as laser sources for the breakdown. Various arc-suppression schemes for CRT systems were evaluated for future use. View full abstract»

    Performance models of suspend locks in operating systems are developed and analyzed. Analytical expressions and algorithms for numerical results have been obtained for an arbitrary number of processors, an arbitrary number of tasks, and one suspend lock. The results are discussed and important dependencies among the major characteristic quantities such as queue length, processor speed, number of p... View full abstract»
