CANUNDA-HP: High-power Laser Beam Shaper

The CANUNDA-HP beam shaping modules can be used to shape high-power continuous lasers. They can perform symmetrical (ring, or ring with a central spot) or asymmetrical shaping, such as a spot followed by a line.

CANUNDA-HP modules have been integrated in industrial environments with optical fiber lasers on robot arms. The shaping module can either be fitted directly to the laser connector and integrate the entire optical chain up to the machining plane, or it can be integrated into standard, off-the-shelf collimation and focusing optical instruments.

Category: Laser Beam Shaping - CANUNDA

Designed to improve laser processing, the CANUNDA range provides versatile and effective laser beam shaping. CANUNDA improves the quality, precision, speed and stability of processing for all types of laser source, whether single-mode or multimode.

The CANUNDA range of fully reflective solutions ensure stable, low-loss beam shaping capable of withstanding the high power of cutting or welding lasers or the high energy levels achieved by ultrashort pulse lasers for micromachining processes.

The fully reflective design of the shaping module supports very high average power (16 kW, demonstrated in partnership with the Institut Maupertuis). It can be cooled in a homogeneous manner for optimal results, thus minimizing thermal focus shift.

All parameters given at 25 °C operating temperature and 1070 nm operating wavelength unless otherwise stated.

Additive manufacturing

Improved quality for laser-based additive manufacturing processes with CANUNDA-HP. CANUNDA-HP provides optimal beam shaping, allowing more progressive heating and cooling, which stabilizes the process and reduces projections. CANUNDA-HP can generate standard ring shapes, or more complex symmetrical (ring with a central spot) or asymmetrical shapes.

Faster processing by optimal beam splitting with CANUNDA-HP. Parallel laser processing is key to improving efficiency, and Cailabs’ technology optimally splits the laser energy to allow several parts to be manufactured in parallel, or the same part to be manufactured by agglomerating the metal in several places at the same time.

Finally, CANUNDA-HP products can be easily integrated into a robot arm with an optical fiber laser.

Laser welding

Improved stability of laser welding processes with CANUNDA-HP. CANUNDA-HP provides optimal beam shaping, allowing more progressive heating and cooling during welding, which stabilizes the keyhole and reduces projections. CANUNDA-HP can generate standard ring shapes, or more complex symmetrical (ring with a central spot) or asymmetrical shapes.

Very high-power welding with CANUNDA-HP, which allows the welding of very thick metal sheets (several tens of millimeters). CANUNDA-HP products have already demonstrated that they can be used for welding up to 16 kW (the maximum available during tests). However, the fully reflective design of the module and the optimal cooling from the rear of the optics would allow beam shaping at an even higher power.

Longer welding times time with CANUNDA-HP. CANUNDA-HP beam shaping and transmission systems provide excellent performance for reducing defocus events (focus shift) during the process. This allows very large parts to be welded for several minutes. In addition, the shaped beams have very long depths of field, allowing the process to adapt easily to the flatness of the parts to be welded.

Laser cutting

Faster continuous-wave, high-power laser cutting processes with CANUNDA-HP The power output of continuous-wave lasers makes it possible to cut thicker sheets. However this is done at the expense of cutting speed, which is limited by the absorption of the material. The speed can be improved by depositing energy in an optimal manner, for example, by asymmetrical beam shaping using MPLC technology. CANUNDA-HP products can also be easily integrated into laser cutting heads.

Surface texturing

Improved quality and efficiency of CO2 laser interference processes by generating a square top-hat beam that provides a much more uniform texture when scanning surfaces with CANUNDA-HP. CANUNDA-HP products can withstand very high power, up to 16 kW!
