New Peak Power for Q-Switched Solid State Lasers: ROFIN introduces a new laser of the DS series with 1 kW output power

Hamburg, Germany, April 2009 – ROFIN-SINAR Laser GmbH in Hamburg broadens its successful high power DQ series of q-switched solid state lasers with the DQ 010.

The high performance lasers of the DQ series are excellent tools for surface applications like ablation, cleaning, insulation and others in development. Cycle times and operating expenses can be reduced with the 1 kW output power and increased pulse peak performances that are 1,000 times higher than CW powers.

ROFIN DQ lasers are established in a wide industrial application area. The DQ 010, with its 1,000 Watt average power, can be integrated with beam switches or power splitter modules allowing the use of one beam source in several production lines. Therefore, investment cost are reduced, while the increased efficiency of the beam source lowers the running costs. The high average power makes it an efficient tool for selective material removal. It is ideal for solar panel ablation, mold cleaning, coating removal, and surface treatment of flat screens.

“We are happy to be able to offer our customers the new top model, the most efficient qswitched
laser in its pulse range. With our power classes of 500 to 800 Watt we were already able to qualify applications with great success, as for example the ablation of aluminum-silicon coatings of high-tensile tailored blanks”, says Markus Rütering, product manager for beam sources at Rofin-Sinar Laser GmbH in Hamburg. “Our experiences show that the lasers of the DQ series make many applications economically or technically feasible for the first time. With short pulses and at the same time high energy we gain low thermal load of the material. This leads to excellent results, for example at the edge insulation of solar cells.”

The lasers of the DQ series can be coupled with fiber optics of 600 or 800 ?m. Compared to round fibers, square fibers provide highest efficiency by machining a bigger area per pulse. Combined with an integrated scanner control, ablation rates of up to 100 cm2/s are possible in diverse applications.

Each DQ lasers is equipped with an optical attenuator for constant pulse energy and long-term stability control. This key feature optimizes application processes by making the pulse energy constant. It provides best
application results for sensitive applications such as the selective ablation of multi-coated surfaces. Its constant performance and repeatability make it suitable for 24/7 production operation.

The new DQ 010 will have its debut at the LASER fair in Munich from 15. - 18. June 2009. We are looking forward to your visit at our booth in hall C2, stand 359.
