Next generation 808nm laser diode bars
At Photonics West 2008, Bookham will show the first products from the new platform that will enable higher efficiency and increased power resulting in reduced energy consumption and thermal loads.
Bookham has announced the launch of its next generation 808nm multi-mode high power laser diode bar portfolio, with the fully qualified products delivering in excess of 60W in continuous wave operation for pumping and fibre-coupled applications The 40W 30% fill factor and 60W 50% fill factor 808nm laser diode bars, available on passive cooler and micro-channel cooler, are designed to deliver higher power, improved efficiencies and extended lifetimes to customers' laser systems

High power laser diode portfolio expands
Bookham, a provider of optical components, modules and subsystems, will unveil an expanded portfolio of high power laser diode products at Photonics West, later this month
To achieve full qualification, the gold-tin hard-soldered laser diode bar products have successfully passed rigorous hard pulsed lifetests, including accelerated long-term operation at 100W for the 50% Fill Factor device.
"This new generation of 808nm product is built on a proven semiconductor material structure that will allow us to grow this portfolio of products, increasing output and offering customers a scalable solution to deliver greater power and reliability in their laser systems," said Bookham senior product line manager, Christian Naumer.
"In the Bookham facility, we have demonstrated up to 130W CW at 50% fill factor with this product; this first launch is just the start of a portfolio that will see Bookham positioned as the leader in high power 8xx products, matching our high power, high brightness and high reliability leadership in 9xx and 10xx products".
The new bars offer low divergence in the fast and slow axis, enabling cost-effective side-pumping and fibre coupling, reducing losses and improving coupling efficiencies.
The next generation 808 products are available in highly customised configurations, including multi-bar arrays.
In addition to showcasing its technology at the exhibition, Bookham will be presenting three technical papers at associated symposium Lase 2008: 'Recent developments for Bar and Base: setting the trends', 'Emission wavelength stabilisation in broad area lasers coupled to fiber Bragg gratings' and 'Performance and reliability of pulsed 1060nm laser modules'.
