A remote laser powered ocean observation buoy is established to obtain long-term, continuous and real-time marine environmental data in the sea surface. Laser power at a base station is transmitted over atmosphere to the remote buoy, and provides the electric power for the measurement system and wireless communication unit by high efficiency solar panels. Then the real-time measurement and communication can be achieved. In the experiment, a prototype system of the remote laser powered ocean observation buoy is realized. A 650 nm semiconductor laser and a GaAs solar cell were used to obtain real time temperature data with 3 m distance and 1 Hz frequency by wireless communication. Remote laser powered ocean observation buoy can provide real-time energy supply with simple maintenance and power supply is not susceptible to weather, so that it can achieve long-term, continuous and real-time ocean observation.
