ECE 4760 Final Project: Laser Audio Transmitter
https://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/s2009/dyz2_jl589/dyz2_jl589/
The first circuit, which is similar to the receiver end, is the laser audio transmission circuit. This transmitter works by modulating the amplitude of the laser based on the amplitude of the audio signal that we are trying to transmit. The audio, which is fed to the circuit through a standard 3.5mm audio jack, is sent to an adder circuit.
