  • Laser Beam Expander Theory
    Perfect Gaussian Laser beams are often characterized by. a parameter known as beam divergence. Divergence is the. angular spreading of light waves as they propagate through. space. Even a perfect unaberrated ray of light will experience. some beam divergence due to diffraction effects. Diffraction
  • Phase Conjugate Laser Optics - Preface
    of the gain media induces aberrated thermal lenses, which severely. affects the beam quality. It thus results in wavefront aberrations that reduce the. brightness of the source and that evolve when changing the operating conditions of. the source. Adaptive correction of phase aberrations in a laser
  • Laser Beam Expander Theory (.pdf)
    Perfect Gaussian Laser beams are often characterized by a parameter known as beam divergence. Divergence is the angular spreading of light waves as they propagate through space. Even a perfect unaberrated ray of light will experience some beam divergence due to diffraction effects. Diffraction
  • Bestform Laser Lens Theory (.pdf)
    Simple focusing and collimating of laser light can often be accomplished by using a single lens element. However the focused spot size, energy intensity and image quality are all dependent on, not only the focal length, but also the laser beam diameter, the lens radii and the center thickness
  • Transmission Sphere Selection Guide
    Brief provides a basic understanding of transmission sphere selection for spherical surface testing. A transmission sphere is used to transform the collimated output beam of the interferometer mainframe into a spherical wavefront, and is used as a beamsplitter to divide the laser light into separate
  • Novel Interferometer Enables Challenging Measurements
    utilizing a proprietary laser source and patented optical configuration has enabled wavefront measurements which until now have been difficult or impossible to complete with standard temporal phase-shifting systems. This article describes a short coherence Fizeau interferometer and its applications
  • MICRO: Product Technology News (May '2000)
    The FPA-5000ES2+ KrF scanner accommodates devices with either 0.18- and 0.15- um design rules. Using a 2-kHz excimer laser, the scanner has improved throughput compared to previous tools and can expose 125 200-mm wafers per hour. The platform can be field converted from a 200- to 300-mm wafer
