Abstract：In this paper, the current development trend of UAV laser communication payload technology is comprehensively reviewed, and its key technologies and application prospects are deeply analyzed. With the increasing maturity and wide application of UAV technology, laser communication has become a research hotspot in the field of UAV communication due to its advantages of high speed, large capacity and strong anti-interference ability. At the beginning of this paper, the research background, purpose and significance of UAV laser communication for promoting the development of UAV technology and improving the efficiency of data transmission are described. In the part of technology development status, this paper reviews the main products and systems of UAV laser communication payload in detail, analyzes its market size and growth trend, and reveals the booming development trend in this field. Then, the paper deeply analyzes the four key technologies of UAV laser communication: laser transmitting and receiving technology, high-precision pointing and tracking technology, signal processing and decoding technology, and anti-interference and secure communication technology, which together constitute the core of UAV laser communication system. However, UAV laser communication still faces many challenges in practical applications, such as atmospheric environment interference, high-precision acquisition and tracking technology problems, lightweight payload miniaturization and integration challenges, and standardization and interoperability issues. To solve these problems, this paper proposes a series of optimization strategies, including introducing advanced atmospheric channel compensation technology, developing high-precision acquisition and tracking technology, promoting light miniaturization and integrated design of payload, and strengthening standardization and interoperability research. These strategies aim to improve the performance stability, reliability and applicability of the UAV laser communication system, and promote its application in a wider range of fields.
