Product Selection Differences for Tunable Lasers

When selecting tunable lasers, there are several key differences to consider:

1. Wavelength Range: Different tunable lasers operate in various wavelength ranges. Consider the specific wavelength range required for your application.

2. Tuning Range and Resolution: The tuning range specifies how much the laser wavelength can be varied, while tuning resolution refers to the smallest wavelength step that can be achieved. Choose a laser with an appropriate tuning range and resolution for your needs.

3. Tuning Speed: This refers to how quickly the laser wavelength can be changed. Faster tuning speeds may be important for certain applications.

4. Output Power: Consider the required output power for your application and choose a tunable laser that meets those power requirements.

5. Laser Linewidth: The linewidth of the laser determines the coherence and spectral purity of the light. It is important to select a laser with an appropriate linewidth for your application.

6. Reliability and Stability: Look for tunable lasers that offer good reliability and stability over time to ensure consistent performance.

7. Control and Automation: Consider how easy it is to control and automate the tuning process of the laser, especially if you require precise and repeatable wavelength tuning.

8. Cost: Different tunable lasers vary in cost, so consider your budget constraints when selecting a tunable laser.

By considering these factors, you can choose a tunable laser that best fits your specific requirements and application.
