Modular Laser Options for HX Laser Launch

The large total laser power required for a ground‐to‐orbit laser launch system can be provided economically by an array of independent beam modules, each consisting of a laser, telescope, and tracking subsystem plus support hardware. This approach radically reduces development cost and risk compared to a single large laser system. This paper discusses requirements and options for lasers and other beam module subsystems for a 100‐MW‐class launch system.
