Properties Of A Coaxial Cw Co₂ Laser, T.-K. Cheng Ken, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A cw CO₂ laser has been developed in which the active medium is formed by a discharge between coaxial electrodes. The laser gain and saturation properties have been studied as functions of the various device parameters. Over-all efficiency is about the same as for a conventional longitudinal discharge laser, and advantages of the coaxial geometry include low voltage operation, rapid cooling, and rugged construction.

Introducing The Secondary Student To Sculptural Design And Form In Metal: Welding Sheet Steel Using The Oxyacetylene Torch, Philip John Smith

Dissertations and Theses

This thesis deals with the application of simple oxyacetylene welding techniques to the secondary art curriculum. Welded sculptural forms in sheet steel have been the focus of my own work during the past three years and these experiences formed the basis or background of the presentation of these skills to secondary students. An instructional unit was designed to fulfill three primary objectives. First, to familiarize the student with the basic tools and materials used in the construction of welded steel sculpture; second, to introduce the student to the creative concepts involved in the creation of sculptural form; third, to give …

A Feasibility Analysis Of A Directly Sun-Pumped Carbon Dioxide Laser In Space, Seiichi Morimoto

Dissertations and Theses

The possibility of using sunlight to pump a CW carbon dioxide laser has been analyzed. Such a laser could be of interest for such applications as space communication and power transmission. In order to optically pump CO₂ using sunlight, the intense vibrational-rotational absorption bands of CO₂ in the 4.3 micron spectral region would have to be utilized. The total pumping power from sunlight can be calculated from the known data of the solar spectral irradiance outside the atmosphere and the infrared absorption by carbon dioxide at 4.3 microns. The pumping power is proportional to the collector area of …

Scalar‐Wave Approach For Single‐Mode Inhomogeneous Fiber Problems, Lee W. Casperson, Cavour W. Yeh, W. P. Brown

Electrical and Computer Engineering Faculty Publications and Presentations

It has generally been accepted that accurate results may be obtained using the scalar‐wave approach to solve problems dealing with inhomogeneous multimode guided‐wave structures. The problem of the applicability of the scalar‐wave approach to obtain wave propagation characteristics in single‐mode fiber or integrated optical circuit guides with inhomogeneous index profiles is examined in this paper. It is shown that if certain limiting conditions are satisfied, the scalar‐wave approach will yield valid results for single‐mode structures. These limiting conditions are usually satisfied by many practical single‐mode inhomogeneous fibers or IOC structures.

The Design And Construction Of A Flashlamp-Pumped Frequency-Doubled Dye Laser Applicable To Long Path Monitoring Of Air Pollutants, Joel Craig Johnson

Dissertations and Theses

The subject of this thesis is the development of a laser light source which could be used in an air pollution monitor to measure the average concentration of sulfur dioxide gas over long paths (>1 km). Many of the problems encountered in designing a long-path pollutant monitor such as instrument cost and reliability, the selection of an optimum spectral region for making the measurement, and light losses due to scattering and turbulence, are considered. The result of these considerations together with a survey of available laser light sources suggested that a frequency-doubled dye laser possessed several advantages over other …

Beam Deflection In A Pulsed Chemical Laser Amplifier, J. Munch, Lee W. Casperson, E. C. Rea

Electrical and Computer Engineering Faculty Publications and Presentations

Analyses and experiments have been performed to investigate deflection of a Gaussian beam propagating through an amplifying medium possessing a strong transverse gain gradient. The analysis includes effects due to dispersion and gain steering. The experiments were performed in a high power pulsed chemical laser amplifier using a cw frequency stabilized laser as a source. Time dependent beam deflection due to the interaction of the gain gradient with the finite radius of curvature of the propagating beam was observed.

Scattering Of Focused Beams By Tenuous Particles, S. Colak, Cavour W. Yeh, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

This paper deals with the problem of the scattering of focused laser beams by tenuous particles using an iterative technique. The results are shown to be accurate provided that (a) the polarizability of the particle medium is small and (b) the phase shift of the central ray is less than 2. It was found that when the size of the incident beam waist is close to that of the scatterer, the scattered field deviates significantly from that for the incident plane wave case. Specific examples are given.
