| Abstract: | The ratiobetween the coherent and incoherent densities of a coherent harmonic generation FEL isproportional to the square of the modulation rate of the spontaneous emission spectrum ofits optical klystron. Therefore enhancing the modulation of the spontaneous emissionspectrum of an optical klystron is important for coherent harmonic generation. A coherentharmonic generation experiment is under way on the 800MeV electron storage ring atUniversity of Science and Technology of China. A modulation rate of 0.8 of the spontaneousemission spectrum of an optical klystron has been obtained. This paper reports themeasurement and enhancement of the modulation rate. |
