Next-generation high-power laser diode pump modules

Fiber lasers have become indispensable in various industrial applications due to their efficiency and versatility. One of the key factors now considered in the industry is the cost per watt of output power. We report on a new generation of high-power, highly efficient laser diode pump modules capable of delivering over 1.5kW of power at 975nm. This development is fueled by enhancements in epitaxial design, chip design, and packaging technologies, which significantly enhance performance without sacrificing the reliability of laser diodes and pump modules. By improving efficiency and leveraging IPG's state-of-the-art high-volume scalable technology, these advanced laser diode chips and pumps reduce the overall cost per watt, ensuring consistent quality and availability.
