DLF Diode Laser Series

High Power Fiber Coupled Diode Lasers

The Visotek DLF Series is a high power fiber coupled diode laser with multiple options and combinations of output powers, wavelengths and fiber sizes. You can acquire a single diode laser module or a turnkey system, that is integrated with the laser module and peripheral components; such as the controller, power source and cooler.

The diode laser module consists of a high-power, semiconductor laser stacked array and optical components that enable the beam to be efficiently coupled into a detachable and interchangeable, single step index fiber. Fiber diameters range from 600 microns to 1,200 microns with output powers from 300W to multiple kW. Fiber lengths up to 50 meters and longer allow remote and flexible laser power delivery.

Customized systems are available upon request and may include processing optics for laser welding, cladding, cutting and high speed scanning. Aiming lasers and monitoring sensors, such as cameras and pyrometers, are available to complete the system. “Fail-Safe” technology ensures reliable and safe operation.

The high integration of the lasers ensures minimal installation time and greater uptime.

Visotek offers a wide range of controllers which can be customized to your needs. Options include micro controllers, PC controlled units or we can integrate standard industrial controllers that are used elsewhere in your operation. The system is capable of managing individual and multiple DLF units simultaneously.

Our fiber coupling delivers a uniform laser beam directly to the workpiece, thus eliminating the cost, complexity and risks associated with mounting the diode laser head to a robot or gantry. If your diode laser application does not require fiber coupling, Visotek can also provide direct diode lasers. We offer everything from single diode emitters, to single bar packages, all the way to stacked arrays and modules with customized beam shapes.
