Coherent Diode Array for High Power Optical Transmitter

ABSTRACT: In this project, a high power laser transmitter will be designed and demonstrated suitable for satellite communication. The laser source will consist of a high-power diode laser array with the individual laser elements coherently combined using a Self-Fourier cavity to provide a high-power diffraction-limited output. Standard modulation techniques will be used suitable for satellite communication. The diode array, external optics, power supply, and control electronics will be designed for operation in a harsh radiation environment. BENEFIT: The successful development of this technology will enable the realization of more efficient and powerful optical transmitter, which in turn will enable longer range and more reliable communication. The simplicity of this technology and reduced part count will lead to fewer failure rates out in space. The compact and lightweight nature of this system will enable more space applications. The higher efficiency of this system will lead to significantly less heat required for dissipation. The technology can also be used for other applications such as long range sensing and Directed Energy applications.
