I am working on a laser-based communication system for underserved areas, where a solar panel is used as a receiver and a laser as a transmitter. However, I am facing challenges in achieving the required signal strength due to limitations in laser capacity and solar panel conversion rates. I am exploring the possibility of modulating the laser signal onto sunlight to amplify the signal. Has anyone explored or achieved success in modulating laser signals onto sunlight? Are there any theoretical or practical limitations to this approach? Any insights or suggestions would be greatly appreciated.
