Raycus Fiber Laser Source Repair

Original‑factory technical team background, proficient in underlying principles of Raycus light sources

Our core engineers are ex‑Raycus staff from its R&D and after‑sales departments. They are well‑versed in optical‑path layouts, circuit logics and factory‑standard assembly of Raycus fiber laser sources.

Our team has in‑depth knowledge of key components such as forward / reverse combiners, gratings, mode strippers and pump arrays. Instead of simple part‑replacement repairs common in the industry, we trace faults from both optical and circuit perspectives for accurate troubleshooting.

In‑depth diagnosis via host‑computer software to pinpoint root‑cause failures

Upon receipt, lasers are unpacked and connected to Raycus dedicated host‑computer software. We check power‑on alarms, red‑light indicators and retrieve historical fault logs.

Real‑time data including pump current, temperature and output power are captured to identify latent soft faults: intermittent alarms, power decay and occasional beam loss. Detailed inspection reports are provided with transparent repair proposals to avoid over‑repair.

Rich practical experience in high‑power laser maintenance

We repair full‑range Raycus lasers, including 10 000‑W‑class high‑power units for cutting, welding, cladding and cleaning.

For dual‑combiner lasers, most optical failures stem from the reverse combiner, which bears total laser power due to back‑reflected light. Failures are mainly caused by poor water‑cooling, reverse optical feedback, pump power surges and coupling bubbles.

Representative cases: we restored full power for a 15 000 W unit with burnt reverse combiner at a sheet‑metal factory; eliminated random shutdowns for a 3 000 W laser used in auto‑part welding; repaired multiple older lasers with aged power modules. Practical maintenance advice on cooling, cutting‑head care and stable power supply will be shared after repair.

Complete spare‑parts inventory with over 100 power‑module variants in stock

Our warehouse stocks combiners, pump modules, gratings, mode strippers and other core parts covering legacy and latest Raycus models. More than 100 types of power modules are kept on‑site.

Repairs are completed in a clean working area, covering combiner replacement, pump‑fiber splicing, grating splicing and signal‑fiber processing. Pump sources will be replaced if power output remains insufficient. Ready‑to‑use spares greatly shorten customer equipment downtime.

Standardized testing and clear post‑repair warranty

Every repaired laser goes through multi‑stage tests: no‑load commissioning, gradual power ramp‑up, 100 % full‑power verification and over 8‑hour water‑cooled loaded burn‑in test. Only units meeting factory specifications will be packed and shipped.

We provide mail‑in repair and on‑site assessment services. All repairs carry warranty, with clear quotations and zero hidden costs, supporting laser processors and integrators to resume stable production.
