ZURICH , Switzerland , June 6 /PRNewswire-FirstCall/ -- Bookham, Inc.(Nasdaq: BKHM), a leading provider of optical components, modules and subsystems, is to unveil a new "Very High Brightness" (VHB) laser diode bar atLASER World of Photonics 2007 in Munich later this month.

The VHB bar has a power output of 80W -- up to four times the brightnessof a typical 10mm bar -- and measures only 3.6mm in width. With a bar smile ofless than 1um -- a record for a hard-soldered device -- the product isdesigned for efficient beam shaping and will enhance the performance of directdiode and fiber delivery systems, particularly those supporting industrialmetal processing applications such as coating, cladding and welding.

"Bookham is leading the market in terms of brightness and power," saidBerthold Schmidt, director of product marketing for High Power Lasers atBookham. "Designed for efficient beam shaping, and with a wall-plug efficiencyof more than 60%, our high power laser diode portfolio enables more reliable,smaller, less expensive and more flexible designs for direct diode systems andfiber lasers."

Visitors to the Bookham stand (number B3.149), will also see new 10xxnmbars designed to provide an additional wavelength to scale power of directdiode systems or to replace Nd:YAG lasers in medical applications. Twoconductively cooled 9xxnm high brightness bars -- a 60W 20% fill-factor barand an 80W 30% fill-factor bar -- will also be on display.

At LASER, Bookham will partner with customers to demonstrate endapplications of its laser diode products. Demonstrations will include CW andpulsed fiber lasers for material processing, micromachining and medicalapplications besides many others.
