Bookham Launches New High Power 808nm Laser Diode Bar

Bookham, Inc. (NASDAQ:BKHM), a provider of optical components for industrial applications, has launched a new high power 808nm laser diode bar that can enable direct energy laser systems and range guided imaging for defense and security applications. The 100W bar also supports DPSS laser systems, including Rod and Slab lasers, as well as direct diode systems for flat panel displays and silicon annealing.

The bar on microchannel cooler provides a rated power of 100W in CW and hard-pulse on/off operation. The laser diode bar boasts an industry leading wall plug efficiency of 59 percent and a 50 percent fill factor to enable higher power output from a larger emitter area. The extended wavelength range also includes 793nm, important to 'Eye Safe' applications based on thulium laser systems. The new product is being launched at this week's SPIE Defense, Security and Sensing event, taking place in Orlando, FL, and will be on show at the Bookham booth (#114).

"This new 100W laser diode bar, together with the 60W conductive cooled bar released at Photonics West 2009, continues our strength in 808nm products and enhances our offering to high value markets such as defense and security," said Christian Naumer, Senior Product Line Manager at Bookham. "We work closely with our customers to identify new applications for their laser systems and ensure that our products meet their requirements while always delivering higher power, higher brightness and higher reliability."

Like all Bookham High Power Laser products, the front facet of the bar is protected against Catastrophic Optical Damage by the E2 mirror passivation process. Telecom grade AuSn (gold tin) hard solder makes the product suitable for demanding industrial and defense applications in CW and hard pulse operation mode.
