Laser Diode Price

Laser diode prices vary widely, from under $1 for basic low-power units to tens of thousands of dollars for high-power or specialty devices.

Price Range

The cost of a laser diode depends heavily on wavelength, output power, spectral properties, package type, and quantity. Basic consumer-grade diodes, such as red lasers for pointers or optical mice (630–670 nm), can cost less than $1 to a few dollars per unit. High-power or specialty diodes, including narrow linewidth, single-mode, or fiber-coupled modules, can range from hundreds to tens of thousands of dollars depending on specifications.

Factors Affecting Price

Wavelength: Common wavelengths for consumer electronics or telecommunications are cheaper due to high-volume production, while specialized wavelengths for biomedical or industrial applications are more expensive. Output Power: Higher power diodes generally cost more, and price differences between manufacturers can exceed 50% for similar specifications. Package Type: Standard diodes are cheaper, while advanced modules with integrated cooling, pilot lasers, or fiber coupling are more expensive.

Quantity: Bulk orders reduce the per-unit cost, while single-unit purchases are typically higher.

Where to Buy

Authorized distributors like Mouser and DigiKey offer a wide selection of laser diodes with transparent pricing and same-day shipping options. Specialty suppliers like Roithner Laser provide detailed price lists for UV, violet, blue, green, and red diodes, often used in research or industrial applications. Online marketplaces like eBay can offer competitive prices for both new and surplus diodes, though quality and specifications should be verified.

Summary

Laser diode prices are highly variable. For basic low-power diodes, expect $1–$10, while high-power, narrow-linewidth, or fiber-coupled modules can cost hundreds to tens of thousands of dollars. When purchasing, consider the wavelength, power, package type, and intended application, and compare prices across distributors and suppliers to find the best option for your needs.
