To increase the effective pulse rate of a light source in a lidar system, a controller provides control signals to the light source to transmit a light pulse once the previous light pulse has been received. The controller may communicate with a receiver in the lidar system that detects received light signals. In response to detecting a received light signal, the receiver may provide an indication of the received light signal to the controller which may in turn provide a control signal to the light source to transmit the next light pulse. The receiver may also provide characteristics of the received light signal to the controller, such as the peak power for the received light signal, the average power for the received light signal, the pulse duration of the received light signal, etc. Then the controller may analyze the characteristics to determine whether to transmit another light pulse.
