Abstract
In one embodiment, a lidar system includes a pump laser configured to produce pulses of light at a pump wavelength. The lidar system further includes an optical parametric oscillator (OPO) with an OPO medium configured to: receive the pump pulses from the pump laser; convert at least part of the received pump pulses into pulses of light at a signal wavelength and pulses of light at an idler wavelength; and emit at least a portion of the signal pulses. The lidar system also includes a scanner configured to scan the emitted pulses of light across a field of regard and a receiver configured to detect at least a portion of the scanned pulses of light scattered by a target located a distance from the lidar system. The lidar system also includes a processor configured to determine the distance from the lidar system to the target.
