Used Fiber Laser Sources

The DMK Repair Center maintains a long-term inventory of a large number of engineering-grade and used fiber laser sources. With a complete range of models and broad power coverage, all units undergo careful maintenance and standardized testing by experienced engineers. They deliver sufficient output power and stable operation, ready for production immediately upon installation. Priced far below new equipment, they are a highly cost-effective choice for laser equipment repair and replacement, old-machine upgrading, and spare unit inventory.

Equipment Source & Quality Assurance

Inventory equipment includes two categories: engineering machines and used machines. Engineering machines are units used for manufacturer R&D testing or exhibition demonstrations, featuring short operating hours, excellent condition, and well-maintained internal components. Used machines are market-recovered units that have passed comprehensive inspection and refurbishment to meet production standards. All units, upon arrival, undergo a complete inspection process including output power calibration, beam quality analysis, optical path coupling inspection, cooling system testing, communication function verification, and item-by-item checks of internal optical modules and power modules. Any aged or defective components are replaced without exception, ensuring every unit shipped meets power standards and delivers stable performance.
