Generation of an intense, directed, ultrashort electromagnetic pulse
Lazarev Yu. N., Petrov P. V.
A superluminal electron-current pulse might be used to generate a high-power, ultrashort pulse of electromagnetic radiation with a small diffraction divergence. The power would be W^IO9 W, the pulse length Γ0^10"12 s, and the diffraction divergence </v<10~4. The current pulse would arise when the plane front of pump light capable of causing electron emission is incident obliquely on a plane metal surface. © 1994 American Institute of Physics.
