Diode Laser (1.3 kW) exhibits 30% efficiency.
August 9, 2011 -
Requiring minimal maintenance due to passive cooling, LIMO1300-F200-SL808/9xx-EX1472 can be used for thermal conduction and deep penetration welding of metals. Fiber coupling through high-end beam shaping lends to wall-plug efficiency of 30% (including cooling), and defective fiber-optic cable can be replaced without readjustment. Additional features include variety of interfaces to PLC and field busses of all types as well as CE-conformant configuration of safety-relevant interfaces.

1.3 kW diode laser with 30-percent efficiency
LIMO Lissotschenko Mikrooptik GmbH, located in Dortmund, world market leader in the field of refractive micro-optics, is increasingly conquering the world of laser systems. The latest example bears the nondescript name, LIMO1300-F200-SL808/9xx-EX1472, but it is a special type of "green system" in the truest sense of the word. The beam-shaping experts have developed a new 1.3 kW diode laser that has wall-plug efficiency of 30 percent, (including cooling). A comparison with systems in the same power class: A typical CO2 laser has an efficiency of approximately six to eight percent and a fibre laser has an efficiency of 20 to 25 percent. Thanks to the efficient fibre coupling through high-end beam shaping, the new system offers excellent wall-plug efficiency. In addition the system is practically maintenance-free, thanks to the passive cooling that dispenses with micro channels. This means: The diode laser significantly lowers the operating costs for energy and maintenance.
"This is an extremely compact solution for cutting and welding that is easy to integrate and practically maintenance free", said Dipl.-Ing. Peter Bruns, Director of Application and Technical Service (ATS). "The user can implement it for thermal conduction welding and deep penetration welding of metals - in addition, for the first time it can be used as a competitive alternative for laser fusion cutting of stainless steel, aluminium and titanium, as well as for laser frame cutting of structural steel and copper."
Yes, but what does a job shop do that has already spent a lot of money for Nd:YAG laser systems, including peripheral devices? It is easy to get started with the economical diode laser because the user can also use standard process heads for the diode laser. Additional unique selling points facilitate the change: Defective fibre-optic cable can be replaced without readjustment. In addition, industrial standard beam delivery systems (LLK-B fibre connectors including breakage and plug monitor) are used. When machining aluminium materials, higher process speeds are achieved than are achieved with well-known radiation sources because a wavelength at which the aluminium absorbs the most power is used intentionally.
Additional advantages: A variety of interfaces to PLC and field busses of all types (Ethernet, CAN, Profibus) and CE-conformant configuration of safety-relevant interfaces. LIMO delivers the compact, modular laser system with an easy-to-replace diode laser module, on which there is a guarantee of three years. LIMO relies on this new type of economical and low-maintenance jack-of-all-trades. Bruns: "A 2-kW version that is ready for series production will follow by the end of the year. Then in 2012 we will bring a diode laser on the market with a four-kilowatt power rating that has the same beam quality and technology."
