Optimization of power output and study of electron beam energy spread in a Free Electron Laser oscillator

Lasing conditions of a free electron laser with helical wiggler

“…As with vacuum-tube devices, FEL devices can be divided into two classes: amplifiers and oscillators. [8][9][10][11][12][13][14][15][16] We employ a simple approach to find the lasing conditions of a FEL resonator with helical wiggler in the general form. Recently, the simulation and optimization of FEL amplifiers in the wide spectrum of wavelengths have been carried out in more realistic physical situations.…”
