Fiber-Coupled Diode Lasers – Mobile Power
Fiber-coupled diode lasers of the LDF series offering 100 W to 15,000 W output power deliver the laser beam to the workpiece through an optical fiber.
Depending on the laser power, optical fibers of 200, 300, 400, 600, 1,000 and 1,500 µm diameter are used. The optical fibers are equipped with sensors to monitor temperature and breakage and can be simply plugged in and exchanged.
Fiber Lasers
In most cases, fiber-coupled diode laser heads are integrated into the compact and mobile supply unit in an all-in-one concept. In conjunction with stack and fault management, the supply unit guarantees maximum reliability in serial production. The laser system can be upgraded and adapted to different applications, for example, by adding diode laser stacks.
Multiple Station Operation with Fiber Lasers
he diode lasers of the LDF series are particularly well suited to multiple station operation with beam switches and fibers of up to 100 m in length.
The beam switch is integrated in the laser head and may also be added later, as customer requirements in production increase. It is equipped with an integrated status monitor and beam absorber.
The mobility and compactness of the diode lasers allow for completely new redundancy strategies in multiple station operation.
Processing Optics with Fiber Lasers
There are currently two diameters of processing optics available for fiber-coupled diode lasers: 25 mm (1") or 50 mm (2"). Both can be easily complemented with sensors for process monitoring and control, for example, for weld seam monitoring.
The spot dimensions of the fiber-coupled lasers can be adjusted within a wide range to suit the particular application and can also be widened using special homogenization optics to form a uniform rectangle, line or square.
Special Processes with Fiber Lasers
Thanks to standardized fiber connectors, other manufacturer’s specialized processing heads such as welding optics, cutting heads or nozzles for cladding, can easily be used together with diode lasers from Laserline.
