DILAS, the diode laser company 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.
The module is based on DILAS’ tailored bar architecture. This innovative platform combines optimized chip structures with high brighditness 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.
240W of scalable output power is delivered out of a 200µm, NA 0.22, modestrip cladding power free, non-detachable, pigtailed 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.
These tailored bar based, fiber-coupled modules target a wide range of high-power fiber-laser pumping applications in industry, research and development, as well as in direct diode applications.
