Two new fibre coupled diode laser arrays from Coherent offer substantially higher brightness than previously available from the company, without any sacrifice in reliability or lifetime
Specifically, the Fap 200 delivers either >50W at 976 m or >30 at 808 m from a 200um core diameter fiber with a numerical aperture (NA) of 0.22.
The Fap 400 provides either >40W at 880 m or >45W at 808 m from a 400 m core diameter fibre having a 0.22NA.
Both these high brightness fiber coupled diode laser arrays utilise Coherent's AAA (aluminium-free active area) technology to achieve industry leading 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.
