Self-adjusting laser–target system for laser fusion

An analysis is made of methods of increasing the radiation density in laser fusion facilities. The utilization of wavefront reversal by a stimulated-Brillouin-scattering (STBS) mirror substantially reduces the requirements for the manufacturing precision of the optical components, structural rigidity, and target feed precision. A detailed analysis is made of the optical and energy characteristics of such a system. Estimates show that a target chamber of ~1.5 m radius can be used with a focusing zone of ~10^–3 cm diameter.
