Abstract: Laser communication under wireless communication domain for transmission of voice. The application purpose of our project is communication, which would be underwater uni-axially transmitted light signal through Laser torch which will act as a carrier between transmitter and receiver. The focus of this project will be Visible Light Communications (VLC)[1]. The project is divided into two main sections transmitter and receiver. The main component in the transmitter is the Laser which can cover distance up to 500m, if any obstruction comes in the path of the beam no sound will be heard at the receiver. The main component in the receiver is the photo-transistor which converts the light energy into electrical energy............
