As demand for high-precision distance measurement, 3D perception, and remote sensing continues to grow, LiDAR technology is playing an increasingly important role in autonomous driving, surveying, mapping, and industrial sensing.
At the heart of every LiDAR system is its laser source. The performance of the laser directly influences signal quality, detection capability, and overall system reliability.
To address these requirements, Lumispot has developed its 1550nm Pulsed Fiber Laser, an advanced laser source designed for LiDAR applications. Combining narrow-pulse technology, high peak power output, and eye-safety-oriented wavelength selection, this solution provides a reliable foundation for next-generation TOF LiDAR systems.
1. Why 1550nm Matters for LiDAR Technology
Wavelength selection is a critical consideration in LiDAR system design.
Compared with conventional 905nm laser sources, 1550nm lasers offer an important advantage in eye-safety engineering. At this wavelength, optical radiation is absorbed more strongly by the anterior structures of the eye rather than being focused onto the retina.
This characteristic allows 1550nm LiDAR systems to explore higher permissible emission levels under applicable laser safety limits, supporting the development of long-range sensing solutions.
For applications involving outdoor environments, dynamic targets, and human-occupied areas, 1550nm laser technology provides an attractive option for balancing detection performance and safety requirements.
2. Supporting Precise Measurement with TOF Technology
Time-of-Flight (TOF) is one of the fundamental principles used in LiDAR distance measurement.
A TOF LiDAR system emits short laser pulses toward a target and detects the reflected optical signals. By measuring the time difference between transmission and reception, the system calculates the distance to the target.
Lumispot’s 1550nm Pulsed Fiber Laser is designed to support this process through its nanosecond-level pulse output and adjustable repetition frequency.
With a typical pulse width of 3ns and an adjustable repetition frequency ranging from 100kHz to 2000kHz, the laser provides flexible operating conditions for different LiDAR system architectures.
Its peak power can reach up to 3kW under specified operating conditions, helping provide the optical signal strength required by demanding ranging applications.
3. Advanced Technologies Behind Stable Laser Performance
To meet the requirements of precision sensing systems, Lumispot integrates several key technologies into its 1550nm Pulsed Fiber Laser.
Narrow Pulse Driving and Shaping Technology
Nanosecond-level pulse generation supports precise timing measurements, providing an important foundation for high-resolution TOF ranging.
ASE Noise Suppression Technology
Amplified Spontaneous Emission (ASE) can introduce unwanted optical noise into laser systems. Lumispot’s ASE suppression technology helps improve output signal quality and supports reliable signal detection.
Narrow Pulse Amplification Technology
Optimized pulse amplification enables high peak power output while maintaining narrow pulse characteristics, supporting demanding LiDAR transmission requirements.
Laser Integration Technology
Integrated optical design contributes to a compact laser source that can be incorporated into different LiDAR system architectures.
Low-Power and Low-Repetition-Frequency Design
Optimized operating characteristics help address the power consumption and system integration requirements of specialized laser sensing applications.
