About Us

As the leading manufacturer of diode lasers for material processing, Laserline and its products have become synonymous with this innovative technology. Diode lasers are used in production processes worldwide and are efficient and reliable in a wide range of applications.

Founded in 1997, Laserline was a pioneer in the world of diode lasers for industrial material processing, and within a short time, the company established itself as the market’s technology leader. Laserline continues to dominate the industry, and the company’s headquarter in Muelheim-Kaerlich, Germany will allow for future growth. One of Laserline´s subsidiaries is located in Shanghai, China. Service and sales engineers work together to provide the best service for our customers. As we continue to grow, we always look for new employees in Germany as well as in China.

The company’s success can be attributed to the competence of its employees – specialists and multifaceted experts from different fields who work together to create innovative and technologically advanced products.

 

 

1997: 

Dr. Christoph Ullmann and Volker Krause founded Laserline GmbH in the Koblenz Technology Centre. These two technology pioneers developed and sold the first direct diode lasers – at the time with the design of a photo camera from the fifties with powers of 500, 900, and 2000 W. The company and its products will be introduced to the general public for the very first time at the fair LASER World of Photonics (Munich, Germany). Laserline’s first industry application is the wire-based laser cladding. Here, the Laserline diode laser is integrated into a high-speed milling machine.

 

1998: 

At the first “StartUp” competition for new businesses – organized by Sparkassen, McKinsey and the magazine STERN – Laserline becomes the Rhineland-Palatinate state winner and ranks third nationwide. The award is personally handed out by the former President of the Federal Republic of Germany, Roman Herzog, and is confirmed by a further success in the industry: Laserline’s diode lasers are used in plastic processing for the very first time.

 

1999:

The world’s first multi laser system for plastic welding is equipped with Laserline’s diode lasers: the company outperforms all competitors and receives the order to deliver a hundred multi diode laser systems. Furthermore, at the fair LASER World of Photonics, Laserline presents the first fiber coupled diode laser with 500 W power and 600 µm optical fiber. Suitable for metal cutting, it makes an application accessible even though it was hitherto considered unattainable for the diode laser technology.

 

2001:

The company’s swift growth requires an increase in capacity: in the presence of numerous representatives from the local government, the ground-breaking ceremony takes place for the new Laserline premises situated in Mülheim-Kärlich, Germany. Product development is also proceeding rapidly: fiber coupled diode lasers are now available with powers of 2000 W (1000 µm fiber) or 4000 W (1500 µm fiber). By connecting 500 W diode lasers with a scanning system, the first dioscan system for quasi simultaneous plastic welding is created. Highlight of the year: AUDI is the first automotive manufacturer to use Laserline’s diode lasers for brazing tailgates – a milestone in the industrial applications of this nascent technology.

 

2002:

Laserline says goodbye to Koblenz Technology Centre and moves into its own premises in Mülheim-Kärlich. Meanwhile, the company now counts 35 employees. Altogether, the 2,500 m² operating area now offers enough space for further growth. 200 guests attended the inauguration ceremony on 14.11.2002. The guest of honor was the Rhineland-Palatinate Minister-President, Kurt Beck. 

 

2003:

The beam quality of fiber coupled diode lasers is optimized: 850 W laser powers are available via 400 µm optical fiber with numeric aperture (NA) of 0.2; 4,000 W via 1,000 µm fiber with the same NA. To increase availability, the lasers can now be equipped with an electronic stack management. The management system recognizes a defect laser stack, turns it off, and automatically values the new characteristics of the laser. Also new is a teleservice: a system failure can be diagnosed worldwide online, and customers get support via telephone. Also, the application range has been increased: Laserline’s diode lasers can now be used for repair welding in oil production.

 

2005:

The power of direct Laserline diode lasers is from now on increased to an unmatched 10,000 W. Furthermore, Laserline can significantly improve the beam quality of its fiber coupled diode lasers for the second time within a very short period. Specifically, there are now laser powers of 400 W via 400 µm fiber, 3,000 W via 600 µm fiber, and 6,000 W via 1,000 µm fiber available with numeric apertures (NA) of 0.2. 

 

2006:

In the course of its continuously growing international business, Laserline opens its first subsidiary at the Silicon Valley, California. Laserline’s diode lasers are used for the tape laying of fiber composites for the first time, amongst others in aerospace, oil and automotive industries.

 

2007:

By building a new production hall, its premises in Mülheim-Kärlich are expanded to 4.300 m². At the LASER 2007 in Munich, Laserline exhibits a fiber coupled diode laser with 4,000 W laser power via 400 µm fiber. Until then, a comparable connection of beam quality and power was only reached by lamp-pumped Nd:YAG lasers.

 

2009:

Laserline sells its 1,000th diode laser and brings to the market the world’s first diode laser with a beam quality of a lamp-pumped Nd:YAG laser (30 mm mrad) with laser powers of 4,000 W. The third highlight of the year: Laserline is qualified by AUDI as a beam source supplier for aluminum welding. The first application field is the welding of tailgates for the AUDI Q5.

 

2011:

Appropriately, at the product-site, the next power performance boost can be registered: since the LASER World of Photonics, fiber coupled diode lasers with 15,000 W output power via 1,000 µm fiber have become available. At the end of the year, three new additional subsidiaries will be opened in Asia: Shanghai/China, Seoul/South Korea, and Tokyo/Japan. Meanwhile, over 110 employees are working for Laserline worldwide.

 

2012:

Laserline’s growth shows no sign of slowing down. By building a new production hall and a new office building, the total area of its premises in Mülheim-Kärlich is now 7,400 m². In several plants for welding of tailored blanks, Laserline’s diode lasers have successfully replaced the until then established CO2 lasers. Essential for the customer’s choice is the high efficiency of the diode lasers.

 

2014:

In April, Laserline opens a new sales department in the premises of the US Fraunhofer Institute in Detroit. The number of employees in the company headquarter in Mülheim-Kärlich is growing continuously, reaching about 200 in October. The maximal power of Laserline diode lasers can be doubled within a year to 40,000 W, a prototype with this output power is presented at the LASYS in Stuttgart. Additionally, Laserline also sets up its new OTS-5 stainless steel optics. Diode lasers are now used in the additive manufacturing of components: diode laser-based cladding makes it possible to produce the desired shapes and structures almost without material loss, rework or tool wear in only one single step.

 

 

2015:

Laserline now counts more than 230 employees. In September 2015, a new production hall with a connected development center was opened. At the LASER World of Photonics, Laserline introduces the new product family LDF of the meanwhile 6th generation to the market. Furthermore, for the first time a prototype with 50,000 W output power is presented.

 

2016:

At the end of the year, a new sales department is opened in Sao Paulo, Brazil. Worldwide, Laserline now counts more than 260 employees. Brazing with a triple spot module, developed by Laserline, has attracted much attention and is rated as an advanced procedure for brazing hot galvanized sheets in the automobile industry. 

Our Chinese subsidiary is located in Shanghai, China. It was founded in 2011. With 14 employees it is our biggest foreign location. Sales engineers as well as service engineers work here together to provide the best service and sales experience for our customers.
