Abstract
A scannerless amplitude-modulated (AM) semiconductor lidar (or laser radar) using frequency-modulation continuous wave ranging (FM/cw) techniques is one of the most promising research directions at present. In this lidar system, the high-power AM laser source is a key component of the lidar transmitter. First of all, we present here the architecture of an FM/cw scannerless AM ladar and summarize and analyze various schemes of high-power laser modulation. Then we put forward a new method for obtaining a high-power AM laser output, that is, to compose a two-dimensional (2D) array light source with laser diodes (LDs) and electro-absorption modulation modules (EAMs). Finally, the optical properties of electro-absorption modulated laser arrays are briefly analyzed. The analysis shows that the modulated laser arrays have the features of integration and miniaturization and can realize incoherent light illumination in the far field. This laser array is potentially a more ideal high-power AM laser source applied to an FM/cw scannerless imaging lidar.
