研究目的
To review the main technologies involving lasers currently deployed in space, the requirements for lasers to be reliable in the space environment, and the advantages and drawbacks of replacing standard technologies with newly developed photonic laser-based devices.
研究成果
The review illustrates the conservative attitude towards the use of laser technologies in space applications, with most deployed devices being semiconductor laser diodes or using an Nd:YAG crystal as the active medium. It emphasizes the importance of space qualification for new laser devices and the potential of novel laser sources and amplifiers to bring significant improvements or enable new applications.
研究不足
The review highlights the challenges and limitations of deploying laser technologies in space, including the need for devices to withstand harsh environmental conditions, the high cost of space missions, and the difficulty of maintenance once devices are deployed.
