Osram Opto Semiconductors SPL BKxx-40WFT laser bars

Osram Opto Semiconductors’ laser bars offer efficiency of up to 65% at 200 W optical output power and can simplify the design of laser systems and reduce their cost.

The bar series, designated SPL BKxx-40WFT, produces infrared radiation in various wavelengths ranging from 915 to 1020 nm. As a result of their efficiency, the bars achieve a long operating lifetime, amply meeting the requirements for industrial laser systems.

Besides the optical pumping of fibre lasers, direct processing of metals - welding, brazing, cutting, hardening, cladding and coating - for use in motor vehicle manufacturing is one of the main applications of infrared lasers with more than 1 kW of power.

Direct diode lasers are the most efficient laser light sources for such fibre-coupled systems and are a more efficient alternative to the carbon dioxide lasers that have been traditionally used.
