Raycus 260W 915nm Fiber-Coupled Diode Laser Pump Source – B-Stock

This listing offers a fully functional Raycus 260W high-power infrared diode laser module, sold as a B-stock or refurbished unit ideal for R&D, prototyping, repair, and budget-conscious industrial applications. As a decommissioned or repaired pump source, it provides substantial cost savings while delivering robust 260W optical output at 915nm wavelength. The module comes with a standard fiber pigtail and is perfect for users experienced with integrating high-power laser diodes into cooling systems and drive electronics.

Important Note: This is a used/refurbished industrial component. It requires proper handling, appropriate supporting equipment (constant current driver, active cooling), and strict adherence to operational guidelines to function safely and reliably.

Technical Specifications & Condition

• Optical Output:

  • Power: 260W nominal (tested before shipping, report provided).

  • Wavelength: 915nm (±3nm). Invisible infrared light – exercise extreme caution.

  • Spectral Width: < 5nm FWHM (typical).

• Electrical Input:

  • Drive Requirement: Constant Current (CC) DC Source.

  • Operating Voltage: ~2V (typical).

  • Operating Current: ~18A DC.

  • Threshold Current: ~3A (approx.).

  • Warning: Cannot be connected directly to a battery or voltage source without current regulation.

• Fiber Output:

  • Type: Standard low-cost silica fiber (jacket may show signs of prior use).

  • Core Diameter: Typically 400µm or 600µm (varies per unit, specified in test report).

  • Connector: Standard output ferrule (bare fiber or simple connector, depending on unit). Note: Fiber is fragile. Replacements are available.

• Thermal Management (CRITICAL):

  • Cooling: Mandatory external heatsink/active liquid cooling required during operation.

  • Max Case Temperature: 40°C during operation for stable power. Power degrades above 45°C.

  • Critical Temperature: 65°C – risk of permanent catastrophic failure.

• Physical & Environmental:

  • Condition: Used/Refurbished. Cosmetics may vary. Fully tested for power output.

  • Optics: May be bare emitter (collimated version) or fiber-coupled. Includes protective window/lens where applicable.

  • Storage: Store with positive/negative terminals shorted to prevent ESD damage. Environment: 8-40°C, <15% humidity recommended.

Critical Operational & Safety Warnings

FOR EXPERIENCED USERS ONLY. INVISIBLE INFRARED BEAM HAZARD – CLASS 4 LASER PRODUCT.

1. Thermal Management: You must provide an adequate heatsink or water-cooling plate. Monitor temperature continuously. Operation without cooling causes instant failure.

2. Drive Electronics: Must use a constant current laser diode driver (18A, compliance voltage >2.5V). Incorrect driving destroys the diode.

3. Beam Hazard: Output is invisible 915nm IR. Always use appropriate IR sensor cards or a camera to visualize the beam. Never look into the beam or its reflections.

4. Material Compatibility: Effective on wood, dark paper, steel, and some dark plastics. DO NOT use on copper, aluminum, or mirrored surfaces – high reflectivity can damage the laser diode.

5. Fiber Handling: The attached fiber is a consumable. Avoid sharp bends. If the output end burns, it can be re-cleaved with a fiber cleaver. Handle with care.

6. Optics Protection: Keep optics clean and free of dust/water. Maintain distance when processing metals to avoid splatter damaging the output lens/fiber tip.

7. Storage: Always short the input pins together when not in use to prevent Electrostatic Discharge (ESD) damage.

Applications (Ideal For)

• Prototyping high-power laser systems.

• Replacing a failed pump module in existing equipment.

• DIY and research projects requiring substantial IR laser power (cutting, welding experiments).

• Educational demonstrations (with strict safety protocols).

• Thermal processing of compatible materials.

Ordering Information (SKU Details)
