DILAS 888nm 50W High-Power Laser Diode Module | 60A Power Supply | Industrial Pulled Component

This listing is for a decommissioned DILAS brand high-power laser diode module. It is a pulled part (removed from a larger system) featuring an 888nm wavelength and a rated 50W optical output. Designed for demanding industrial applications, it requires a high-current 60A power supply. This component is sold as-is, tested for basic function where possible, and is intended exclusively for engineers, researchers, repair technicians, and advanced hobbyists seeking a professional-grade laser diode for custom projects, system repair, or experimental use. This is not a new or retail product.

Technical Specifications

• Laser Diode Specifications:

  • Brand / Origin: DILAS (Recognized industrial laser diode manufacturer).

  • Wavelength: 888nm (Near-Infrared, invisible to the naked eye).

  • Optical Output Power: 50W (Nominal, as per original specifications).

  • Beam Quality: Multi-mode, typical for high-power diode stacks.

  • Spectral Width: Typical for broad-area diodes (several nanometers).

• Electrical & Drive Requirements:

  • Operating Current: Approximately 60A (Specific I/V curve to be determined by the user. This is a critical parameter.)

  • Operating Voltage: ~1.8V – 2.2V (Typical for diode stacks, varies with temperature and current).

  • Drive Requirement: MUST use a professional, high-current Constant Current (CC) Laser Diode Driver capable of delivering 60A+ with proper voltage compliance and soft-start.

  • Threshold Current: Typically 5-10% of operating current.

• Physical & Thermal Specifications:

  • Module Type: Conduction-Cooled Package. Typically a hard-anodized aluminum or copper block with a mounting surface.

  • Cooling Requirement: MANDATORY ACTIVE COOLING. Requires a substantial heatsink or, more likely, a water-cooled cold plate with significant thermal capacity to handle >100W of waste heat. Thermal interface material (paste/pad) is required.

  • Fiber Output (If Applicable): May or may not include a fiber pigtail. This varies per unit. Specify if a fiber-coupled unit is required.

  • Condition: Used / Pulled. Shows signs of previous installation (mounting marks, possible solder residue). Cosmetic condition varies. Fully tested for basic electrical continuity and diode junction function. Optical power output is NOT guaranteed to be 50W.

  • Connections: Typically has + (anode) and – (cathode) terminals for power, and possibly a thermistor or monitor photodiode.

Key Features & Potential Applications

• Industrial-Grade DILAS Quality: Benefits from the robust construction and engineering of a leading OEM laser diode supplier.

• High-Power 888nm Output: Useful wavelength for pumping certain solid-state laser crystals, material processing (e.g., plastics welding), medical/therapeutic equipment, or specialized infrared illumination.

• Cost-Effective for Projects: Provides access to a high-power laser diode at a fraction of the cost of a new OEM module.

• For Experienced Integrators Only: This is a core component requiring significant expertise in high-current circuit design, thermal management, and laser safety to implement successfully.

• Potential Uses (for qualified individuals):

  • Repairing or Rebuilding a commercial laser system that uses a similar DILAS module.

  • Custom High-Power IR Light Source for experimental or research setups.

  • DIY Solid-State Laser Pumping Project.

  • Integration into a custom material processing or heating system.
