1550nm Seed Laser for LiDAR: Redefining Precision in Mapping Applications

What is LiDAR-based Mapping?

LiDAR-based mapping is a cutting-edge geospatial technology that captures high-precision topographic and environmental data by emitting laser pulses and analyzing their reflected signals. It revolutionizes geographic surveys, urban planning, environmental monitoring and resource exploration, providing centimeter-level accurate 3D spatial data for various industries. Unlike traditional mapping methods, LiDAR mapping breaks through the limitations of manual surveying and optical imaging, realizing efficient and all-weather data collection in complex terrains such as mountains, forests and urban canyons.

How 1550nm Seed Laser Empowers LiDAR Mapping

Wuhan Siyou’s 1550nm Seed Laser   is the core light source of high-performance LiDAR mapping systems, and its technical advantages are perfectly matched with the core demands of mapping applications. The laser operates at a wavelength range of 1547.5nm to 1552.5nm (at 65℃, pulse mode), featuring eye-safe performance, high peak power and narrow linewidth—three core characteristics that form the technical foundation of its application in mapping.

In the technical architecture of LiDAR mapping systems, the 1550nm Seed Laser  serves as the seed light source to generate stable laser pulses, which are amplified by the subsequent optical amplification module and then emitted through the beam scanning system (such as Risley prism scanner). The emitted 1550nm laser pulses have excellent atmospheric transmission performance, which can effectively reduce the attenuation caused by fog, dust and other atmospheric factors during long-distance propagation. After the laser pulses hit the ground, terrain or target objects, the reflected echo signals are collected by the receiving optical system and coupled into the photoelectric detection module through the G657A2-HTA optical fiber of the laser. The laser’s high SMSR (≥35dB) and low noise performance ensure the clarity of the echo signal, and the short pulse width enables the system to capture fine topographic features, realizing high-resolution 3D point cloud data acquisition.

In addition, the laser is equipped with TEC temperature control and 900μm high-temperature resistant optical fiber tube, which can maintain stable performance under harsh field mapping environments (even for long-term operation above 105℃). Its 55% typical coupling efficiency ensures the efficient transmission of optical signals in the system, reducing energy loss and improving the working efficiency of the mapping LiDAR. Whether it is airborne aerial mapping, vehicle-mounted ground survey or satellite-borne remote sensing mapping, this laser can provide continuous and stable light source support, ensuring the accuracy and integrity of mapping data.
