How much does an 830nm laser diode cost

The price of 830nm laser diodes varies widely, ranging from around $100 for low-power pigtailed modules to several thousand dollars for high-power fiber-coupled or integrated modules.

Low-Power Laser Diodes

For laboratory or OEM applications, low-power 830nm pigtailed laser diodes (1–100mW) are available. For example, Edmund Optics offers a 100mW pigtailed module with an integrated driver for plug-and-play operation, typically priced around $100–$200 depending on accessories and configuration . These are ideal for experiments requiring single-mode fiber coupling and simple integration.

Medium-Power Laser Diodes

Fiber-coupled 2–5W 830nm laser diodes are available from suppliers like AeroDIODE and QPhotonics. Prices for these modules generally start at $500–$1,500 for 2–3W versions and increase with power and additional features such as polarization-maintaining fibers or fiber Bragg gratings for narrow spectral output . These modules often include TEC regulation and air cooling for stable operation.

High-Power Laser Diodes

High-power 10–20W multimode 830nm laser diodes are offered as turnkey modules with integrated drivers and fiber coupling. Prices for these units can range from $2,000 to over $5,000, depending on the fiber type, connector, and additional control options . These are suitable for industrial, medical, or bioengineering applications requiring high brightness and stability.

Online Market Options

For more flexible or lower-cost options, eBay lists 830nm laser diodes, including 2W fiber-coupled modules, often priced between $150–$400, though availability and quality may vary . This can be a cost-effective option for prototyping or hobbyist use.

Summary

• Low-power (1–100mW): ~$100–$200
• Medium-power (2–5W): ~$500–$1,500
• High-power (10–20W): ~$2,000–$5,000+
• Online marketplaces: ~$150–$400 for used or small modules The final price depends on power output, fiber type, packaging, and integrated control electronics, so it is recommended to contact suppliers directly for quotes tailored to your specific application .
