Abstract: A lidar system which includes one or more light sources to produce one or more optical signals and a demultiplexer to separate the one or more optical signals into a plurality of sub-portions which may be distributed to a plurality of sensor heads. The sensor heads emit the sub-portions of the one or more optical signals into a plurality of fields of view and to detect reflected or scattered light from the fields of view. The lidar system also includes one or more optical amplifiers and one or more filters to reduce amplified spontaneous emission produced by the one or more optical amplifiers.
