    AI Overview
    Large fiber diameter (LDF) laser source repair involves specialized fusion splicing and cleaving of cladding diameters ranging from
    125
    𝜇𝑚
     to over
    500
    𝜇𝑚
    , often necessitated by damage from high-power reflections or, to QBH connectors. Key equipment includes high-precision fiber cleavers and LDF splicers (e.g., Shinho S-37) to remove damaged sections and replace or re-terminate the fiber, restoring the beam quality. 
    Key Aspects of LDF Laser Repair 
    • Specialized Splicing: Standard fusion splicers cannot handle LDF. Specialized LDF splicers are essential for treating cladding diameters (125mm-530mm), utilizing split-type indenters to ensure stability.
    • Component Replacement: Repairs often involve replacing the entire fiber cable or damaged QBH output heads rather than just repairing a small section, especially if the internal crystal is damaged.
    • Core Process Steps:
      1. Preparation: Careful stripping of polyimide coatings, which are resistant to conventional methods, often requiring dedicated stripping tools.
      2. Cleaving: Precision cleaving of the large fiber.
      3. Splicing: Using a specialized LDF splicer to join the fiber.
      4. Cleaning & Protection: Cleaning QBH protective windows with alcohol and cotton swabs.
      5. Re-coating/Reinforcement: Using adhesive, UV light curing, and protective foil tape.
    • Required Tools: Large-diameter fiber fusion splicer (e.g., Shinho S-37), high-precision Cleaver, fiber stripper. 
    Post-Repair Considerations 
    • Environmental Control: The repaired unit must operate in low-humidity environments to prevent condensation, which can cause power failure or damage the laser module.
    • Cooling Water Check: Ensure the water chiller temperature does not cause condensation on the laser module.
    • Safety & Testing: A low-power test cycle (e.g., 10-20%) is recommended to verify performance before resuming normal operation.
