The price of a 940nm laser diode typically ranges from $5 to over $2000 depending on power and configuration, with local costs in Angola likely higher due to shipping and import fees.

International Price Range

• Low-power diodes (≤1W): These are commonly used for hobbyist or sensor applications and can cost around $5–$50 per unit on platforms like AliExpress or Made-in-China .
• Medium-power diodes (1–10W): Suitable for industrial or medical applications, prices generally range from $50–$300 depending on beam quality and packaging .
• High-power diodes (10–200W): These are integrated modules with fiber coupling or specialized drivers, costing $500–$2000+ per unit, as offered by suppliers like AeroDIODE .

Factors Affecting Price in Angola

1. Shipping and Import Duties: International shipping to Angola can add significant cost, often 20–50% above the base price depending on courier and customs fees.
2. Power and Module Type: Fiber-coupled or PM/FBG modules are more expensive than bare diodes.
3. Supplier and Warranty: Reputable suppliers like DigiKey or Laserland may charge more but provide quality assurance and technical support .
4. Bulk Orders: Purchasing multiple units can reduce per-unit cost, especially from wholesale platforms like Made-in-China .

Recommendations for Purchasing in Angola

• Check local distributors: Some electronics suppliers in Angola may stock low- to medium-power diodes.
• Use international suppliers with shipping to Angola: Platforms like AliExpress, DigiKey, or Laserland can ship directly, but confirm customs clearance and shipping fees.
• Consider module requirements: For industrial or medical use, ensure the diode comes with proper drivers and thermal management to avoid damage. In summary, while a basic 940nm diode may cost under $50 internationally, high-power or specialized modules can exceed $2000, and local prices in Angola will likely be higher due to shipping and import costs .
