LIDAR Lasers

Lidar Lasers are a crucial part of LIDAR systems.  LIDAR Systems utilize the light generated by these LIDAR Lasers to illuminate targets or scene with pulsed laser light and measure how long it takes for reflected signals to be returned to a receiver. This information, combined with other data recorded by the system, generates a precise, three-dimensional map with details about the shape and surface of the imaged area.  A lidar system includes a laser source (transmitter), a sensitive photodetector (receiver), synchronization and data processing electronics, and either motion-control equipment or solid-state microelectromechanical systems (MEMS)-based components for precise laser scanning to create 3D maps and/or proximity data. See our new Lasers 101 page for in depth information on Solid State Lasers.

LIDAR Lasers are used in a wide range of applications, including airborne topographic mapping, bathymetry (high-resolution mapping of the sea bottom and coastal areas), and lidar for Autonomous vehicles. The wavelength and specifications needed for these applications vary widely, system designers need to understand the physical environment and performance objectives of their application.

For airborne topographic mapping, high peak power, nanosecond pulses, and a wavelength around 1 µm are typically used, in which case the beam is expanded large enough to be considered eye-safe.

For bathymetry, a high-energy, frequency-doubled 532 nm laser source is often used, as the green wavelength represents the best compromise between high transmission in pure water and limited backscattering from submarine particulates.

LIDAR for autonomous vehicles and other high-performance compact lidar for civil and commercial applications, often utilize lasers with a wavelength deemed as eye-safe.  Among eye-safe wavelengths, IR lasers emitting around 1.5 µm are often the choice when solid bodies need to be detected as in topography mapping and obstacle avoidance. At the 1.5um wavelength, the atmosphere is quite transparent, and detectors are very efficient.
