II-VI Introduces 1kW Version of 900 Direct Diode Laser Engine

II‐VI Incorporated of Pittsburgh, Pennsylvania USA, reported that its DirectProcess 900 direct diode laser engine is now available with 1 kW continuous output power. The device comes with network interfaces for Industry 4.0. The company notes that the increasing number of applications in industrial materials processing, including cutting, joining, and hardening is stimulating the demand for industrial lasers that are more energy and process efficient.

New 1 kW Direct Diode Laser for Welding and Cutting with Clean Edges

II-VI’s DirectProcess 900 leverages the company’s in-house design and manufacturing expertise in diode lasers, high-power laser optics, and laser light cables to deliver high wall-plug efficiency. The company says that the laser’s superior beam uniformity and top-hat intensity profile, with a beam parameter product (BPP) of less than 8 mm x mrad, can enable welding with
clean seams and cutting with smooth edges, thereby reducing or even eliminating post-process steps on metals including steel, copper, and aluminum.

“The ability of the DirectProcess 900 to operate at an output power of 1 kW while maintaining low BPP enables a broad range of processing applications on materials such as aluminum and steel, and on mixed materials such as copper-aluminum used in car batteries,” said Haro Fritsche, product line manager, II-VI DirectPhotonics. Fritsche added, “The state of the art management interface to our laser engines greatly simplifies system integration and control of key laser parameters, enabling our customers to leverage the full benefits of direct diode laser processing.”

II-VI says that the DirectProcess 900 product platform can be programmed to perform precisely timed processes, and the device’s its TCP/IP or EtherCAT interfaces allow remote management and diagnosis.  According to II-VI, 1 kW direct diode laser engines are small, lightweight and only 2 RU (rack units) high. Furthermore, the lasers can be deployed along with II-VI’s laser processing heads and laser light cables.
