| 内容記述 | We obtained a monoenergetic electron beam of 7 MeV from a plasma with the electron density of produced by a 2-TW, 50-fs laser pulse with a center wavelength of 800 nm. A clear Stokes satellite peaks were observed in forward-scattered light spectra with monoenergetic electron beam generation. This suggests that the monoenergetic electron beam was generated through an acceleration by a plasma wave. At lower density ( ), a high energy component disappeared, and the observed weak satellite indicated small amplitude of the plasma wave. At higher density ( ), although the number of high energy electrons dramatically increased, the monoenergetic peak disappeared. The observed broad satellite suggests that a wave breaking occurred. These results suggest that there are appropricate conditions for the excitation of the plasma wave for the monoenergetic beam generation. | |||||
