Introduction: Laser audio transmission is a technology that converts audio signals into light signals for wireless transmission. This technology offers high-quality audio with minimal interference, making it ideal for military, aerospace, and high-security applications. However, optimizing laser communication networks in dynamic and variable environmental conditions is a challenge. Factors such as atmospheric turbulence, cloud cover, dust, and weather disturbances may affect the quality and stability of the signal, causing data loss or interruption of communication. The Cryptographic Laser Communication System is designed to eliminate these problems by incorporating security techniques into the heart of the system's operations, developing intelligent algorithms for real-time monitoring, predictive analysis, and dynamic adjustment of transmission parameters based on environmental feedback.

Objectives: The Cryptographic Laser Communication System seeks to enhance the efficiency, reliability, and performance of laser communication networks by integrating AI algorithms into signal transmission processes. The research will address environmental variability, signal degradation, and alignment precision challenges, allowing for high-speed communication over long distances and improved signal processing efficiency

Method: The transmitter will convert the audio to a modulated laser beam for transmission in a wireless system. It will have a MAX4466 microphone for audio capture, PAM8403 amplifiers for signal strengthening, and a laser diode for transmission using PWM or AM modulation. The receiver will use a solar panel as a photodetector, PAM8403 for signal amplification, and a speaker for output. AI-based cryptographic techniques improve security, noise reduction, and error correction. The system was prototyped and tested for signal integrity optimized for real-world conditions. Some of the key components include MAX4466, PAM8403, laser diode, and a 4-ohm, 10-watt speaker for audio transmission with clarity.

Results: The paper discusses a laser-based audio transmission system, transmitting live signals with minimal loss and distortion through advanced encryption and decryption algorithms. It is scalable and adaptable to other optical communication applications, including secure data transfer and remote sensing.

Conclusions: This Cryptographic laser communication system effectively enhances signal quality and reliability by integrating machine learning techniques such as noise reduction, error correction, and adaptive modulation. By leveraging affordable hardware like the MAX4466 microphone and PAM8403 amplifier, the system addresses key challenges in traditional optical communication, offering a cost-effective solution for applications in remote communication and IoT
