Diffraction Loss in Dielectric-Filled Fabry-Perot Interferometers

IEEE Transactions on Microwave Theory and Techniques, 1982
We analyze the transmission of dielectric-filled Fabry-Perot interferometers excited by a spherical wave having a Gaussian amplitude distribution transverse to the axis of propagation. The loss due to diffraction experienced by the incident mode is found to be reduced by a factor /spl ges/ n/sup 4/ when n, the index of refraction of the dielectric, is ...

Threshold Relations and Diffraction Loss for Injection Lasers

IBM Journal of Research and Development, 1963
Mathematical expressions are derived for the minimum current density necessary to cause stimulated emission in injection lasers. A new type of diffraction loss for a thin light-emitting layer surrounded by light-absorbing material is calculated.

Gain reduction in FELs due to diffraction losses

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989
Abstract The asymptotic expressions for the gain in the free electron lasers (FELs), which operate in the strong-pump Compton regime and in the collective Raman regime, and which employ a sheet electron beam and a cylindrical electron beam, are presented.

Diffraction of Fast Electrons After Single Plasmon Loss

Journal of Applied Physics, 1963
The diffraction of eigen-loss electrons is examined in some detail. It is shown that the collision zone with a crystal is sufficiently diffused that a significant fraction (10% at E = 105 V) of E1 = E−δE electrons are produced outside the crystal boundaries.
