Bookham has launched 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 new platform will enable higher efficiency and increased power resulting in reduced energy consumption and thermal loads.


The 40W 30 per cent fill factor and 60W 50 per cent 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.


To achieve full qualification, the gold-tin hard-soldered laser diode bar products have passed hard pulsed life-tests, including accelerated long-term operation at 100W for the 50 per cent fill factor device.



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.
