Laser Technology News 2001 p10:

• MEMS may improve efficiency of space-based solar collectors
  Tiny microelectromechanical systems (MEMS) may be the key to maintaining giant space-based structures, such as solar collectors, according to researchers Steve Tung and Larry Roe at the University of Arkansas (Fayetteville).
• Airborne antimissile laser weapons will require better knowledge of atmospheric particles
  Researchers at Ben-Gurion University of the Negev (Israel) have found that under many atmospheric conditions, suspended aerosol particles in the path of a laser beam will significantly broaden its strike area, thereby decreasing weapon effectiveness.
• Disposable fiberoptics relay real-time data about oil drilling
  A new technique developed at Sandia National Laboratories (Albuquerque, NM; www.sandia.gov) uses a low-cost disposable fiberoptic telemetry system to relay real-time information about oil and gas drilling.
• Flat-panel displays may someday benefit from nanobump fabrication
  Cornell University researchers have discovered a new way to fabricate nanoscale structures on silicon with the potential to fuel the development of products ranging from biological sensors to light-emitting silicon-based displays.
• Adoption of 193-nm lithography seen by 2003
  As the semiconductor industry strives to move beyond 100-nm feature boundaries, the cycle for optical lithographic technology is expected to evolve from a market of early adopters of 193-nm technology in 2001 into a more general mass-market adoption in 2003.
• New laser technique leads to discovery of compounds that might provide treatment for cocaine poisoning
  A new laser-based process to study the regulation of signal transmission between cells of the nervous system has led to the discovery of several compounds that could become the basis for a cocaine-poisoning treatment.
• Lidar system measures upper-atmosphere temperatures at both poles
  A sensitive laser radar (lidar) system, first deployed over Okinawa, Japan, to observe meteor trails during the 1998 Leonid meteor shower, has now been used to probe temperatures in the upper atmosphere over both geographic poles.
• Molecular rulers may help build nanoscale optoelectronics structures
  Scientists at Penn State (University Park, PA) have discovered a precision technique to build ultraminiature metal wires in very close proximity to each other.
• Quantum information processing may no longer face entanglement problems
  Scientists may have found a way to optimize entanglement, a bizarre quantum-mechanical connection that can exist between particles, and is an essential component in many quantum-information-processing applications, such as quantum computation, teleportation, and cryptography.
• Fiber-optic sensors may soon ride the rails
  Researchers at the University of Illinois at Urbana-Champaign (UI; Champaign, IL) are fabricating fiber-optic sensors that could someday improve train safety by detecting flaws in rails and wheels.
