Claim 18:
19. An autonomous vehicle, comprising:
a LIDAR sensor system, the LIDAR sensor system comprising:
a light source configured to generate a beam;
at least one optical amplifier configured to amplify the beam to produce an amplified beam;
an optical power distribution network comprising:
at least one input port configured to receive the amplified beam;
one or more optical splitters configured to split the amplified beam into a plurality of distributed beams;
a plurality of output ports respectively configured to provide the plurality of distributed beams; and
one or more optical isolators configured to attenuate reflected signals at the plurality of output ports by coherently interfering the reflected signals;

a transmitter configured to receive the plurality of distributed beams;
one or more optics configured to emit the plurality of distributed beams at a target; and
a receiver configured to receive a reflected beam from the target and determine an object detection associated with the target; and
