New Architecture Delivers Industry Leading Reliability, Power Efficiency and Design Flexibility

MILPITAS, Calif., January 23, 2007 – JDSU, the leading enabler of broadband and optical innovation, today announced the launch of its FCD488, the first telecom-based visible solid-state laser designed for biomedical, industrial and semiconductor applications

FCD488 changes the market landscape by shifting from designs based upon free-space optics and specialized manufacturing, to a telecom-based, all-in-fiber design platform that capitalizes on high volume manufacturing processes. The result is increased product stability and reliability.

Key customer benefits of the FCD488 include:

• Fiber Based Architecture – Reduces the complexity of instrument design and manufacturing for customers resulting in faster time to market and reduced need for realignment, which can result in lower cost of ownership.
• Package Size– FCD488’s compact package size, which is a third of the size used in leading competitive architectures, addresses the trend towards smaller end-user device packaging used in biomedical, industrial and semiconductor applications. All control electronics are packaged within the laser head.
• Low Heat Dissipation- FCD488 electrical efficiency equates to less than a third of the heat dissipation in current market offerings.  Unlike the leading competitor offerings, no heat sink is needed facilitating customer integration and enabling smaller, desktop size instruments.
• Telecom Components – FCD488 utilizes components from JDSU’s current telecom portfolio such as diode lasers with a lifetime in excess of 100,000 hours.

“We believe that with the FCD488 JDSU is changing the rules of the game when it comes to high-precision commercial lasers,” said Phillip Meredith, senior vice president and general manager for JDSU’s commercial lasers product group.   “Typically, high-precision commercial laser applications have labored under a highly customized environment which can be a time-consuming process.  With the introduction of FCD488, JDSU provides a telecom-based commercial laser platform that offers improved design flexibility, electrical efficiency and increased reliability.”

FCD488 is a continuous wave 10 and 20 mW 488nm laser and is available in two output configurations: free space and fiber delivered.
