Cardiology: Aug 1, 1997 — Keyhole" is the buzzword for lasers in cardiovascular surgery, as it is in many other surgical disciplines. Minimally invasive procedures are being cultivated to reduce the injury and healing time for patients, and reduce the cost for insurance companies. Though techniques such as transmyocardial revascularization (TMR) are in their infancy and the road ahead is admittedly long, lasers could serve a large pool of patients who suffer from cardiovascular disease and the pain associated with it....

Photonics Spectra, Aug 1997
Photonics in Industry: Aug 1, 1997 — Photonics cuts and welds, verifies shapes and labels, and assesses function. It helps produce quality products and verify that quality. Quality issues are the stuff of symposia throughout the world. Every industry faces a steady and increasing...
Photonics Spectra, Aug 1997
Power Generators: Aug 1, 1997 — Energy use is increasing around the world, driven by expanding industry and populations. At the same time, concerns about the environmental impact of generating plants emissions are driving changes in designs and operation. To improve these designs...
Photonics Spectra, Aug 1997
Semiconductors: Aug 1, 1997 — A major change in the semiconductor industry is prompting considerable growth in the demand for instrumentation and manufcturing tools. Wafers are getting larger, and lithography design improvements are narrowing features' the line width and...
Photonics Spectra, Aug 1997
Telecommunications: Aug 1, 1997 — Telecommunications is primarily a photonic endeavor in the 1990s. Optical fiber carries signals from lasers to detectors, which just happen to turn those photons into electrons for the ride to a switch that sends it to a television, a telephone or...
Photonics Spectra, Aug 1997
Imaging with Nonlinear Optics Jul 1, 1997 — One of the more surprising applications of femtosecond lasers is the imaging of sensitive biological structures, which appear to tolerate the onslaught of peak power densities of more that 1011 W/cm2, better than the 105 W/cm2 in a confocal or even...
Photonics Spectra, Jul 1997
Instrumentation Keeps Pace with Pulsed Lasers Jul 1, 1997 — Ss the laser solves more and more problems in industry and the laboratory, applications follow for laser instrumentation that can analyze a laser's power, energy, beam quality and stability. And as the laser expands its abilities to meet the needs...
Photonics Spectra, Jul 1997
Plastic Makes the Grade Jul 1, 1997 — Plastic optics have taken a huge leap taken since the 1960s, when, a plastic magnifier epitomized the technology's high end. Today, the plastic diffractive optics landscape can only be described as dynamic.Plastic diffractive optics are finding...
Photonics Spectra, Jul 1997
Taking the 'Hype' out of Hyperspectral Imaging Jul 1, 1997 — Since Landsat's launch more than 30 years ago, everyone from agriculturists to utility executives have looked to airborne and satellite spectral imagers to lift the veil of mystery surrounding natural resource exploration and development.System...
Photonics Spectra, Jul 1997
Telecentric Lenses: Gauge the Difference Jul 1, 1997 — For decades, engineers developing metrology instrumentation have used telecentric lenses in their products. Contour projectors and optical comparators, for example, owe much of their measurement capability to these unique lenses.Over the past decade...
Photonics Spectra, Jul 1997
High-Power Lasers: Jun 1, 1997 — If "better, faster, cheaper" is the motto of industry, it follows that the phrase would be the guiding vision of industrial sequipment suppliers, such as high-power laser manufacturers.Laser cut, weld, solder, drill, mark and clad materials in...
Photonics Spectra, Jun 1997
Industry to Researchers: Jun 1, 1997 — Industrial users say they are willing -- eager, even -- to adopt novel manufacturing technologies that can improve their processes and products. "I doubt that you will find a bigger or better audience for your advanced laser technologies, or a...
Photonics Spectra, Jun 1997
Laser Techniques Make Surfaces Spotless Jun 1, 1997 — Surface contamination by microscopic particles is currently one of the most serious problems facing the microelectronics industry. As much as 50 percent of yield losses could be attributable to particulates. Furthermore, as the demand for smaller...
Photonics Spectra, Jun 1997
