Abstract

Among the most expensive and critical components in the transmit laser in a communication terminal are the multimode pump laser diodes used to amplify the laser signal for secure transmission through space. With multiple active laser components in each optical communication terminal, well-demonstrated reliability is a critical factor in the selection of the pump laser diodes. We present a comprehensive study on the qualification of high-power laser diode components for integration into satellite communications. We detail the design and execution of various tests, such as mechanical shock, thermal cycling, radiation exposure, and vacuum chamber trials, to mimic the challenges of space operation. The results of this study not only provide valuable information for the specific laser component under investigation but also contribute to the broader understanding of qualifying optical components for spaceborne systems.
