Case Study

Carbon fiber composite joining using free-space direct diodes

Creare, who’d won an SBIR to develop a laser system that could join ribbons in carbon fiber for aerospace, turned to Lasertel for its expertise in designing lasers.

The existing system, with an indiscriminate heat source, lacked the necessary directional control to precisely process the material. In the initial retrofit design, the customer tried an off-the-shelf fiber coupled laser diode, but this design resulted in a heating head that could not meet size constraints.

Lasertel’s T6 fluid cooled laser diode arrays, in a scalable building block format of 5 bars precisely spaced for even distribution of optical power over the work surface, delivered more power per square cm, to get the beam profile where they needed it, at a significantly reduced head size.

This custom configuration proved to be highly effective in carbon composite joining. Replacing a heat coil or gas jet with Lasertel free-space direct diodes resulted in:

  • 400% materials processing speed improvement
  • Electrical-to-optical efficiency gain over 60%
  • Reduction in rework of 47%, through improved heat targeting and control
