Diffraction loss in radiometry
Applied Optics, 2003Diffraction loss in radiometry has gained in importance recently because of an increased interest in longer wavelengths and the continuous improvement in experimental accuracy. The deviation from geometrical optics now contributes significantly to the errors of experiments.

IEEE Transactions on Magnetics, 1987
The present paper reports theoretical computations of the diffraction loss incurred by magnetostatic forward volume waves (MSFVW's) with propagation in a YIG film as a result of the finite length of the radiating transducer. As in the case of magnetostatic surface waves (MSSW's), this loss is found to decrease with increasing frequency, a feature that ...

Low-Loss Open Resonators and Diffraction Formulas
Applied Optics, 1972Si descrive una procedura basata su un "nucleo iterato n-volte" per valutare numericamente modi e perdite di risonatori aperti con perdite dell'odine di un millesimo o inferiori. Si è applicata la procedura a un risonatore flat-roof con numero di Fresnel N=12.25 e trovato un grande vantaggio nel tempo di elaborazione per esempio con un nucleo iterato ...

On the Diffraction Loss of Optical Resonator
Japanese Journal of Applied Physics, 1966The oscillation characteristics are reported of a helium-neon laser equipped with a resonator which consists of two concave spherical reflectors with non-identical curvatures. Laser oscillations in resonator arrangements of the so-called high loss geometry are studied. The powers and the field patterns of the output beam are shown.

Threshold Relations and Diffraction Loss for Injection Lasers
IBM Journal of Research and Development, 1963Mathematical 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.
