Coherent launches compact, air-cooled 500W diode laser system
Materials, networking and laser technology firm Coherent Corp of Saxonburg, PA, USA has launched the COMPACT EVOLUTION AC, a next-generation compact, air-cooled 500W diode laser system for polymer welding.
Compatible with existing diode laser processing heads, the new system is said to offer superior performance and convenience for a wide range of industries including precision manufacturing, semi & display capital equipment and instrumentation.
Engineered for performance and ease of use, the COMPACT EVOLUTION AC features a 300µm fiber and turnkey operation, supporting critical applications such as polymer welding, soldering, heat treatment, and laser-assisted bonding. Its air-cooled thermal management eliminates the need for external water cooling, making it well suited for high-humid ity environments and streamlined product lines. Delivering up to 500W of continuous-wave output in a compact rack-mountable (19”, 5HU) form factor, the system introduces greater flexibility and simplifies integration for OEMs seeking efficient, high-power diode laser solutions.
“This system is a game-changer for polymer welding, offering unparalleled convenience, efficiency, and power in a compact, air-cooled design,” says Dr Karlheinz Gulden, senior VP, Laser Components and Subsystems at Coherent. “It will enable new levels of productivity and expand the possibilities for our customers in diverse industries.”
The COMPACT EVOLUTION AC is generally available and suitable for both new installations and retrofit applications.
Coherent is showcasing the COMPACT EVOLUTION AC at LASER World of Photonics 2025 in Munich, Germany (24–27 June).
