Power Laser Beaming and Applications in Space

A brief overview of the concept of power laser beaming in space and its applications are presented. A direct solar-pumped iodine laser with the iodide t C & l lasant is described as an example of the power laser system.

Enhancing Fel Power with Phase Shifters∗

Tapering the undulator parameter is a well-known method for maintaining the resonant condition past saturation, and increasing Free Electron Laser (FEL) efficiency. In this paper, we demonstrate that shifting the electron bunch phase relative to the radiation is equivalent to tapering the undulator parameter. Using discrete phase changes derived from optimized undulator tapers for the Linac Coh...

High brightness injector for a high power superconducting rf FEL

We have developed a concept for a high average power FEL which incorporates a superconducting rf linac in an energy recovery configuration to increase the overall efficiency . Our design minimizes space charge effects at low beam energy by using : (1) higher than usual voltages on our grid modulated electrostatic electron gun and (2) pulse widths much longer than usual, from the gun. These puls...
