If I modulated a laser frequency with voice, would a photo cell be capable of receiving that information?

Frequency modulation in a laser refers to the process of varying the frequency of the laser beam in order to encode information, such as voice, into the beam. This modulation allows for the transmission of voice signals through the laser beam.
In a laser, frequency modulation is achieved by changing the intensity of the laser beam at a specific frequency. This causes the laser beam to rapidly switch between different frequencies, which can then be decoded on the receiving end to retrieve the encoded information.
Frequency modulation allows for the transmission of voice signals over long distances with minimal distortion, making it a reliable method for communication. It also allows for multiple signals to be transmitted simultaneously, increasing the efficiency of communication.
One limitation of frequency modulated laser transmission of voice is that it requires a direct line of sight between the transmitter and receiver. This means that obstacles such as buildings or mountains can disrupt the transmission. Additionally, the quality of the transmission may be affected by atmospheric conditions.
Frequency modulated laser transmission of voice has various applications, including long-range communication for military and emergency services, satellite communication, and underwater communication. It is also used in laser microphones for surveillance and in laser-based communication systems for spacecraft.
