Laser Product Highlights 2001 p2:

• Lambda Physik ships 180-W KrF industrial excimer laser
  Lambda's 600K device delivers high power, 180 W, stabilized output energy of 600mJ at 300 Hz. According to company management, pulse energy stability makes this excimer laser ideal for high throughput microstructuring.
• LIGHTech Fiberoptics introduces the smallest mechanical 1x2 switch at ECOC
  The manufacturer of optical switching components, variable optical attenuators, integrated optical modules and test equipment introduced its LT210 series of small-form-factor, opto-mechnical switches at ECOC in Amsterdam. The switches feature a form factor height of 5.5 mm and switching speed of 5 ms.
• UV spot light source includes LCD display
  The Lightningcure LC5 series UV spot light sources from Hamamatsu (Bridgewater, NJ) features a high-durability shutter and LCD display. UV radiant intensity is 3.5 W/cm² (5 W/cm² with a condenser lens). The system also offers a cassette-type lamp that eliminates the task of aligning the optical path and a power outage recover program where the light output restores within 10 s after even a 1-s output.
• System tests laser diodes at the bar or chip level
  The Model 2520 pulsed laser diode test system from Keithley Instruments Inc. (Cleveland, OH) can perform pulsed L-I-V testing up to 5 A and continuous L-I-V testing to 1 A. The system's pulsed testing capability makes it suitable for testing a broad range of laser diodes, including emerging pump laser designs for Raman amplifiers.
• System measures GRIN lenses with a variety of face angles
  The SpectraMet automated inspection system for GRIN lenses from Scion Photonics (Valencia, CA) allows lens quality checks prior to assembly.
• Palomar develops automated production line for optoelectronic packages
  Depending on the package design and requirements, the line can integrate wire bonders with the firm's new In-Situ UV Component Assembly Cell, which is designed to avoid problems inherent with snap cure methods such as out gassing, very small batch sizes, and short work times.
• Trumpf introduces new scanner laser welding system at fiberoptic expo
  The Trumpf Laser Technology Center (Plymouth, MI) unveiled its latest scanner welding technology at the Fiberoptic Automation Expo in Chicago. The Programmable Focusing Optic focuses the laser beam to any defined location on the working area using a series of Galvo mirrors. With an integrated pulsed or CW laser, the device can weld parts without requiring movement of the focusing optics or the workpiece.
• Fiber prep and fusion splicing system is fully automated
  The Presta system, introduced by kSARIA Corp. (Wilmington, MA) at this week's Fiberoptics Automation Expo in Chicago, is reportedly the industry's first fully automated fiber prep and fusion splicing system for fiberoptic module assembly. The new system strips, cleans, cleaves, splices, recoats, and proof-tests up to 40 fibers in a single pass in just one minute per splice with no operator intervention.
• Laser photoelectric offers pinpoint sensing accuracy for ultra thin targets
  The F22 Series PowerTouch laser from Pepperl+Fuchs (Twinsburg, OH) offers a Class II laser light source for pinpoint sensing accuracy that features pushbutton sensitivity adjustment and a programmable optical interface. The system is available in 150-mm and 300-mm range diffused modes, as well as a retro-reflective mode.
• Adept introduces laser bonding photonics assembly solution
  Adept Technology Inc. (San Jose, CA) introduced a new laser welding system for fiberoptics manufacturing at this week's Fiberoptic Automation Expo in Chicago. The NanoBonder LWS system integrates precision motion control, machine vision, alignment stages, and weld process technologies designed to improve throughput and yields by reducing alignment and bonding cycle times.
