Name: Raycus 260W 915nm Fiber-Coupled Diode Laser Pump Source - B-Stock
Brand: LaserOne

Description

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.

Key Features & Package Contents

High Power, Low Cost: Access 260W of infrared laser power at a fraction of the cost of a new unit.
Pre-Shipment Testing: Each unit comes with a specific test report and video demonstrating optical power output.
Industrial Proven: Built on Raycus's reliable diode platform, suitable for demanding applications.
Package Includes:
1. One Raycus 260W Laser Diode Module (condition as described).
2. Fiber optic pigtail attached (length and condition vary).
3. Pre-shipment test report and video documentation.
4. Basic safety and operation guidelines sheet.

Critical Operational & Safety Warnings

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

Thermal Management: You must provide an adequate heatsink or water-cooling plate. Monitor temperature continuously. Operation without cooling causes instant failure.
Drive Electronics: Must use a constant current laser diode driver (18A, compliance voltage >2.5V). Incorrect driving destroys the diode.
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.
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.
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.
Optics Protection: Keep optics clean and free of dust/water. Maintain distance when processing metals to avoid splatter damaging the output lens/fiber tip.
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.
