How to Choose a Laser

1. Manufacturer Matters: Quality and Innovation

A reliable manufacturer is paramount. Look for established companies with a proven track record of producing high-quality laser diodes. Their commitment to research and development ensures access to cutting-edge technologies that can elevate your project’s performance.

2. Wavelength: Tailoring Light to Your Needs

The wavelength of a laser diode determines the color and interaction with materials. Barcode scanners typically utilize a 650nm red wavelength, whereas other applications might require specific wavelengths for tasks like scattering light through smoke or achieving optimal absorption in skin tissue. Cost can also be a factor. Common, high-volume laser diodes (like the 405nm used in Blu-ray) can be cost-effective for certain applications, while others might require precise wavelength tolerances.

3. Power Output: Balancing Performance and Safety

The required power output depends on the application. Patient alignment systems might function well with low-power lasers (<1mW), while 3D scanners might benefit from higher power diodes (>50mW) for improved image contrast. Remember to consider laser safety classifications when selecting power output. It’s generally recommended to choose a laser with at least 20% more power than strictly necessary to account for fluctuations and maximize the diode’s lifespan.
