DILAS launches 240W, 915nm fiber-laser pump module

Diode laser maker DILAS of Mainz, Germany has expanded the wavelength range of its tailored bar-based, scalable concept with its new high-brightness fiber-laser pump module delivering up to 240W optical output power at 915nm.

Based on DILAS' tailored bar architecture, the platform combines optimized chip structures with high-brightness beam-shaping technologies, all assembled with automated production processes. The tailored bar is a monolithic multi-emitter source, allowing the handling of multiple emitters during each manufacturing step, to lower complexity and ease manufacturing. The result is enhanced reproducibility, beam quality and fiber-coupling efficiency, claims the firm.

The 240W of scalable output power is delivered out of a 200µm, 0.22 NA (numerical aperture), mode-strip cladding power free, non-detachable, pig-tailed fiber. In addition, single-wavelength scalability of output power will be available soon by combining several of these modules by spatial and polarization multiplexing techniques into larger assemblies.

The new tailored bar-based, fiber-coupled modules target a wide range of high-power fiber-laser pumping applications in industry, R&D and direct-diode applications.
