摘要：
A relativistic electron beam propagating through a plasma in the ion-focused regime exhibits an electromagnetic instability with peak growth rate near a resonant frequency 22. Growth is enhanced by optical guiding in the ion channel, which acts as a dielectric waveguide, with fiber parameter V1(I/IA)1/2. A 1D theory for a laser making use of this instability is formulated, scaling laws are derived, and numerical examples are given. Possible experimental evidence is noted. © 1990 The American Physical Society.
