PHASE JUMP METHOD FOR EFFICIENCY ENHANCEMENT IN FREE-ELECTRON LASERS

The efficiency of a free-electron laser can be enhanced by the phase jump method.The method utilizes the phase-shifting chicanes in the drift sections between the undulator segments.By applying appropriate phase jumps, the microbunched electron beam can decelerate and radiate coherently beyond the initial saturation, enabling further energy transfe

In the title compound, C16H13FO4, jomeed furniture the aromatic rings enclose an angle of 73.68 (6)°.In the crystal, C—H.O and C—H.F contacts connect the molecules into a three-dimensional network.The shibori dot fabric shortest intercentroid distance between two aromatic π-systems is 3.6679&#8197
