Lamp Pumped YAGs obsoleted by Laserline’s Next Generation Diode Lasers

Laserline maintains its position as the leading manufacturer of high power diode laser systems for industrial applications with its next generation lasers on show at LASER 2009 in Munich.

A vision became reality at the LASER 2009 in Munich: For the first time ever, diode lasers now reach 4,000 W with a beam quality equivalent to that of lamp pumped Nd:YAG systems. Fiber delivered, the beam can be focused down to 0.6 mm with a 200 mm focusing length. Designed with the application in mind, welding processes in steel and aluminum as well as fine cladding are well within the abilities of the new generation of Laserline’s diode lasers. Very high beam quality lasers such as fiber or disk lasers are not necessary, and may even be detrimental when it comes to the ability to bridge gaps or reach a minimum weld width. The next generation diode laser’s beam parameters are tailored towards welding processes, and are offering the most economical solution.

“As in past LASER shows, we again succeeded in doubling the beam quality of our multi-kilowatt diode laser systems,” said Dr. Christoph Ullmann, CEO of Laserline. “This is the result of the continuous development of Laserline’s diode laser technology and our focus on customer’s needs. We are proud to introduce the world’s first 4 kW diode laser matching the beam quality of lamp pumped YAGs.”

With an even smaller footprint, the new generation diode lasers use less than 10 sqft (1 m²), while offering new options such as an integrated chiller allowing the use of plant water of up to 90 F (32°C). A small footprint, low maintenance, and an efficiency of up to 45 % directly translate into real life cost savings, up to 10 times lower than that of a lamp pumped YAG laser. This will pave the way to a replacement of conventional lasers by diode lasers in ever more applications.
