Two fibre coupled diode laser arrays from Coherent offer higher brightness than previously available from the company, without any sacrifice in reliability or lifetime.
The FAP 200 delivers either >50W at 976nm or >30W at 808nm from a 200µm core diameter fibre with a numerical aperture (NA) of 0.22. The FAP 400 provides either >40W at 880nm or >45W at 808nm from a 400µm core diameter fibre having a 0.22NA. Both these high brightness fibre coupled diode laser arrays use Coherent’s AAA (aluminum-free active area) technology to achieve MTTF (mean time to failure) and operating lifetime characteristics.
The FAP 200 and FAP 400 are intended to service a variety of applications in materials processing, such as plastics welding and soldering, as well as solid state laser pumping and therapeutic medical uses. For industrial applications, their higher brightness translates directly into increased process throughput. For laser pumping, high brightness enables increased laser system output.
