General properties of quantum optical systems in a strong field limit
Author(s): Chumakov, S. M.; Klimov, Andrei B.
Abstract: We investigate the dynamics of an arbitrary atomic system (n-level atoms or many n-level atoms) interacting with a resonant quantized mode of an em field. If the initial field state is a coherent state with a large photon ...

Optical analysis of thermal induced structural distortions
Author(s): Weinswig, Shepard; Hookman, Robert A.
Abstract: The techniques used for the analysis of thermally induced structural distortions of optical components such as scanning mirrors and telescope optics are outlined. Particular attention is given to the methodology used in the ...

Optical star coupler with large number of inputs and outputs
Author(s): Saniter, J.; Schmidt, F.; Hermes, T.
Abstract: Attenuation based on the power division is made linearly dependent on the maximum number of inputs and outputs, by cascading coupler elements. The coupler elements are connected together in such a way that only after the ...

Analysis and preliminary design of optical sensors for propulsion control
Author(s): James, K. A.; Quick, W. H.; Strahan, V. H.
Abstract: A fiber-optic sensor concept screening study was performed. Twenty sensor subsystems were identified and evaluated. Two concepts selected for further study were the Fabry-Perot fiber-optic temperature sensor and the ...

N2 pressure - broadened O3 line widths and strengths near 1129.4 cm-1
Author(s): Copeland, G. E.; Majorana, L. N.; Harward, C. N.; Steinkamp, R. J.
Abstract: A Beer's Law experiment was performed with a tunable diode laser to find the N2 pressure broadening characteristics of a single 03 absorption line at 1129.426 cm for N2 pressures from 10 to 100 torr (O3 pressure = 3.16 ...

Integrated optical signal processing with magnetostatic waves
Author(s): Fisher, A. D.; Lee, J. N.
Abstract: Magneto-optical devices based on Bragg diffraction of light by magnetostatic waves (MSW's) offer the potential of large time-bandwidth optical signal processing at microwave frequencies of 1 to 20 GHz and higher. A thin-film ...

Output beam intensity noise induced by fiber perturbations in a fiber-linked laser
Author(s): Hamilton, Jeffrey J.; Pang, YI; Richard, Jean-Paul
Abstract: The effects of acoustic perturbations on an optical fiber intended to link a laser to an optical cavity have been studied. Acoustic noise above the level of -45 dBre (1 microbar) in the frequency band of 500-1500 Hz has a ...
