Various technologies described herein pertain to context aware real-time power adjusting for steerable lidar. A lidar system can include a laser source (e.g., FMCW) configured to emit an optical signal. The lidar system can further include a scanner configured to direct the optical signal emitted by the laser source from the lidar system into an environment. The optical signal can be directed over a field of view in the environment during time periods of frames. The lidar system can further include a controller configured to modulate a power of the optical signal emitted by the laser source between the frames and/or within one or more of the frames. The controller can modulate the power of the optical signal emitted by the laser source based on a position of the lidar system in the environment and a direction in which the optical signal is to be transmitted into the environment.
