Stimulated emission of bremsstrahlung
TLDR
In this article, a formula for the probability of stimulated emission of Bremsstrahlung is derived and it is shown that stimulated emission occurs if the incident electrons travel in a direction roughly parallel to the electric field vector of the wave stimulating the emission.Abstract:
A formula for the probability of stimulated emission of Bremsstrahlung is derived. It is shown that stimulated emission occurs if the incident electrons travel in a direction roughly parallel to the electric field vector of the wave stimulating the emission. Emission from free electrons is used in electron tube devices. The purpose of this paper is to show that stimulated emission occurs already in the elementary process of the encounter of one electron and one nucleus or ion. There is no need for a slow-wave structure or elaborate electron bunching and no need to consider phase relationships. This elementary effect of stimulated emission should lead to a type of oscillator and broadband amplifier working without slow-wave structures or need for the close mechanical tolerances of high-frequency klystrons. A device of this kind may be noisier than a conventional maser. It may be that the effect discussed in this paper is responsible for some of the hitherto unexplained semiconductor diode oscillations which have been reported in the literature.read more

Stimulated Emission of Bremsstrahlung in a Periodic Magnetic Field
TL;DR: In this paper, the Weizsacker-Williams method is used to calculate the gain due to the induced emission of radiation into a single electromagnetic mode parallel to the motion of a relativistic electron through a periodic transverse dc magnetic field.

Collective and single-electron interactions of electron beams with electromagnetic waves, and free-electron lasers
Avraham Gover,Amnon Yariv +1 more
TL;DR: In this paper, a simple comprehensive model is developed to describe electron-beam interaction with an electromagnetic wave in periodic electromagnetic structures, which is general enough to describe both collective and single-electron modes of interaction and quantum mechanical, classical and Fermi degenerate regimes.

Inverse stimulated bremsstrahlung of slow electrons under Coulomb scattering
TL;DR: In this article, a simple analytic expression has been obtained for the rate of inverse stimulated bremsstrahlung of slow electrons scattered by the Coulomb charge Ze, where the initial and final electron energies are assumed to be small compared to the Rydberg energy mZ 2 e 4 / 2.

The Oscillistor—New Type of Semiconductor Oscillator
R. D. Larrabee,M. C. Steele +1 more
TL;DR: In this paper, a magneto-oscillatory effect has been observed in the electron-hole plasma within a semiconductor, which can be produced by such agents as contact injection and optical or thermal excitation of minority carriers.
