Generation of isolated single attosecond hard X-ray pulse in enhanced self-amplified spontaneous emission scheme.
The generation of isolated attosecond hard x-ray pulse has been studied under the enhanced self-amplified spontaneous emission (ESASE) scheme with the density and energy modulation of an electron bunch. It is demonstrated in simulation that an isolated attosecond hard x-ray pulse of a high contrast ratio can be produced by adjusting a driver laser wavelength and the energy distribution of an el...
متن کاملUndulators for Short Pulse X-Ray Self-Amplified Spontaneous Emission-Free Electron Lasers
We review the synchrotron type radiation sources with focus on undulator and freeelectron laser (FEL) schemes, aimed on working in X-ray range and ultra-short time interval. Main FEL schemes, useful for generation of high frequency radiation, extending to X-rays, are presented. High harmonic generation is explored. The advantages and disadvantages of single pass and of multipass designs are dis...
متن کاملAmplified Spontaneous Emission'
We review the coherence properties of the self-amplified spontaneous emission (SASE). Temporally, SASE is similar to the spontaneous undulator radiation except that the spectral bandwidth is about ten times narrower compared with typical undulator radiation. The situation is quite different in the transverse dimension, where SASE is fully coherent. INTRODUCTION Several laboratories are pursuing...
متن کاملCharacteristics of Dual Amplified Spontaneous Emission from MEH-PPV Solutions
We report the observations of dual wavelength amplified spontaneous emission from the solutions of a conjugated polymer poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) in Tetrahydrofuran and 1, 2 Dichlorobenzene. We have prepared MEH-PPV using a modified procedure and purified several times in each step, the material offers low molecular weight, low polydispersity index an...
متن کاملFirst observation of self-amplified spontaneous emission at 1.064 lm
We report evidence of self-amplified spontaneous emission at 1064 nm. Single pass, on-axis microwiggler emissions into a 25 nm bandwidth have been recorded as a function of beam charge, and show a clear enhancement over spontaneous emission after threshold. These are the first measurements of SASE at such a short wavelength, and employ the smallest period wiggler used to date in a successful SA...
