Laser Payloads on Small Satellites

Laser payloads on satellites have the ability to enhance our communications capabilities and information gathering power from space. Implementation of lasers to Lightsats provides one method to assess the effectiveness of these technologies at reduced risk. This paper will focus on the main applications of lasers in space and how laser systems may be adapted to the Lightsat environment. This will include a discussion of the different types of lasers, which types are suitable for space based payloads, and which of these is suitable for what types of applications. Included in this discussion will be the selection criteria based on efficiency, weight, lifetime, size, and complexity. A brief description of diode, solid state, and diode pumped solid state lasers will follow. In addition, a detailed examination of the specific factors that are the driving design considerations for laser payloads will be presented.
