Zm. Dai et L. Xu, 3-DIMENSIONAL THEORY OF AN ION-RIPPLE LASER, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 49(1), 1994, pp. 745-750
We develop a three-dimensional theory of the ion-ripple laser by using
a consistent set of wave and pendulum equations to characterize the c
oherent radiation in the fundamental and harmonic frequencies. The sma
ll-signal gain is obtained by an eigenmode analysis. The optical-guidi
ng effects on the harmonic generation in the linear regime are discuss
ed. Under proper conditions, the ion-ripple laser may provide a practi
cal source of microwaves, light rays, and even x rays.
