A transmitter of a wireless power transfer and data communication system comprising a transmitter system including a transmitter housing, one or more high-power laser sources, a laser controller, one or more low-power laser sources, one or more photodiodes, a beam steering system and lens assembly, and a safety system. High-power and low-power beams are directed to corresponding receivers and transceivers of a transceiver system inside a remote receiver system by the controller and the beam steering system and lens assembly. Low-power beams include optical communication to the transceiver system. The photodiodes of the transmitter system receive optical communication from the transceiver system. Low-power beams are co-propagated with and in close proximity to high-power beams substantially along an entire distance between the transmitter housing and the receiver system. The safety system instructs the controller to reduce the high-power sources in response to detected events.
