1550nm Seed Laser: The Core of High-Precision 3D Scanning and Sensing

Q: Why is 1550nm preferred for 3D scanning and LiDAR?

A: 1550nm is in the eye-safe infrared spectrum, allowing for higher power output compared to 905nm. It also offers superior atmospheric transmission and lower solar background noise, making it ideal for long-range and high-precision sensing.

Q: Does this seed laser support pulsed operation?

A: Yes, it is specifically designed for high-performance pulse mode operation, typically used in Time-of-Flight (ToF) and FMCW LiDAR systems. It maintains a high Side Mode Suppression Ratio (SMSR) even under rapid pulsing.

Q: What is the significance of the integrated TEC?

A: The integrated Thermo-Electric Cooler (TEC) ensures that the laser wavelength remains stable across a wide range of operating temperatures. This is critical for applications like 3D scanning where wavelength drift can lead to measurement errors.

Q: Can Wuhan Siyou provide custom fiber lengths or connectors?

A: Absolutely. As a direct manufacturer, we offer agile OEM services, including customization of fiber types (e.g., PM fiber), lengths, and various connector types (FC/APC, etc.) to match your system's specific requirements.

Q: How does the narrow linewidth benefit industrial metrology?

A: A narrow linewidth corresponds to a long coherence length, which is essential for interferometric measurements used in 3D scanning vibrometers and high-resolution imaging, ensuring precise phase detection and low noise.
