Fibre-coupled diode laser modules

The diode lasers business unit of Jenoptik's Lasers & Material Processing division has introduced its high-brightness fibre-coupled diode laser modules up to 65W optical output power, with 105μm fibre core diameter and a numerical aperture of 0.15.

The laser modules are based on several single emitters coupled together, and are characterised by a high level of robustness and a compact design of 100 x 60 x 25mm dimensions. Due to the passive cooling of the diode laser modules through to the base plate, handling and installing the modules is easy. Another benefit is an integrated filter that protects against back reflection from the fibre laser beam.

The modules are suitable for applications in both optical pumping of fibre lasers and direct material processing.
