LiDAR—Light Detection and Ranging—is a remote-sensing technology that uses pulsed laser light to measure ranges to a target. A sensor uses the laser beam reflected off the object to calculate the distance based on the speed of light. LiDAR applications include autonomous vehicles, wind sensing, metrology and defense.
Fiber lasers are the perfect light source due to their compactness, efficiency and thermal properties. As high peak power is desired, fibers with high absorption are then used in order to reduce nonlinear effects.
