 High
Brightness, Fiber Coupled Diode Lasers |
|||||||
|
High brightness and power, fiber coupled diode lasers are developed delivering 500W from a 200mm fiber, NA=0.2. Wavelength locking for pumping and dense multiplexing is explored for scaling the output power. Keyhole welding of thin metals, i.e. copper becomes possible. Custom systems are built for pumping multi-kilowatt fiber lasers and several industrial applications. Custom systems are built for several industrial applications. Production-ready prototypes are transferred for commercialization while CLT continues improving the technology.

Optical
Design |

|
Some applications in laser welding, cutting or
hardening require tailored specialized beam shapes, additional
process monitoring or scan optics for fast beam positioning for
optimizing the process and productivity. We offer .tailored
light. with advanced monitoring or control options. We provide
advanced optic simulation with Zemax®,
opto-mechanical design, machining, assembly, test and process
development. The modular optic, based on a design of our parent
facility Fraunhofer ILT in Germany enables high flexibility and
fast realization at minimal cost. Additional components can be
realized within days.

Automated
Precision Alignment |
|||||||
|
The precise alignment of the fast axis collimation lens (FAC) relative to the laser diode is essential for the production of beam shaped diode lasers. Due to the short focal length of the FAC (0.6-3mm), the focal distance and the lateral (fast axis) lens position have to be maintained within less than 0.5µm, and the 3 angular degrees of freedom within 0.5 to 20mrad. During precision alignment, the collimated and focused beam are simultaneously observed. Common manual procedures are prone to inconsistency and challenging to integrate QA procedures.
