Up to 10 Laser Diode Arrays Integrated in a Pumping Line

SIRILAS belongs to a group of laser diode arrays with special heat sinks.

Integrated cooling fins on which the laser bar is centered provide effective water cooling. The simple design of the cooling channels counters the possibility of corrosion. An enclosed package protects against dust and contact. An integrated lens produces an almost parallel beam, with vertical divergence of typical one degree.

By integrating these laser diode arrays in pumping lines, RayTools is saving potential customers a major development stage. The result is a ready-to-use module with optimized cooling that can be easily incorporated in the standardized mechanical, thermal and electrical interfaces of a pumping application. By combining multiple pumping lines it is possible to supply high-power solid-state lasers with energy. These are used as alternatives to CO 2 lasers for material processing (for example for welding plastic and metal). The output of a laser system can be further increased by connecting solid state lasers in series.

Solid-state lasers that are excited by diode laser pumping lines are much smaller than CO 2 lasers and operate more efficiently. SIRILAS semiconductor lasers with an efficiency of more than 50% are ideal pumping sources because their output can be precisely tuned to the absorption lines of the solid-state laser materials. This reduces the thermal load on the solid-state laser medium. Efficiency and beam quality are improved. What's more, maintenance is easier because the laser diode arrays can be replaced individually if necessary.
