<p>Lasers have been incorporated into many parts of society including heavy industrial work military defense, light displays, scientific research, and everyday household appliances. Free Electron Lasers (FELs) use relativistic electrons traveling in an alternating magnetic field to produce coherent radiation. One particular application for a FEL is to beam power to satellites. The United States and Russia have agreed to pursue this effort together. The installation in the United States is the SpacE Laser ENErgy (SELENE) project scheduled for installation at China Lake, California. The SELENE laser system consists of an oscillator and a radiator. The electrons are bunched in the oscillator in preparation for entering the radiator. The use of a three-section optical klystron has been proposed for the SELENE oscillator. An optical klystron EEL is composed of multiple undulator sections, each separated from the next by a dispersive section Ths dispersive section alloys for larger gain from a shorter total length of undulator The effects of the optical klystrons in the SELENE oscillator using the proposed SELENE FEL parameters will be investigated through the use of simulations of two and three-section undulators.
