With its new diode lasers from the TruDiode series, Trumpf is entering new dimensions in energy and cost-efficient production. For the first time, diode lasers suitable for industry that achieve a high-performance beam quality that meets the quality of lamp-pumped high-performance lasers are available. Yet with its socket output efficiency level of up to 40 percent, the TruDiode laser is much more efficient. This is why they are designed for welding applications currently performed by high-performance lasers.
With an output of 3 kilowatts, the TruDiode 3006 is the first laser of the new series that TRUMPF will introduce to industry experts at LASER World of Photonics 2009. Additional performance classes with 1 and 2 kilowatts are scheduled.
In addition to high electrical energy efficiency, users also benefit from the advantages of the passively cooled diodes, which contribute considerably to the long service life of the TruDiode laser – and its reduced operating costs. The space-saving, modular design also makes integration of the diode laser into existing production systems easy.
TRUMPF has developed new technological concepts for the TruDiode series to exploit the high efficiency made possible by diode lasers also in direct applications. The heart of TRUMPF’s diode laser is a fiber-coupled diode module with technical performance that has previously been impossible to achieve. It produces an output of up to 100 watts that runs through a 100

micrometer fiber. The numeric aperture contributes less than 0.12. Several of these modules are combined into a laser unit to achieve the desired output. The technology of the TruDiode laser guarantees that the efficiency of the diode modules remains intact in the complete unit and achieves values of up to 40 percent.
