Objectives/Hypothesis: Cricopharyngeus muscle dysfunction (CPD) ranges from asymptomatic cricopharyngeal bar (CPB) to Zenker's diverticulum. Previous work suggests that CPD can result in dilation and weakening of the pharynx above the obstruction. Th

High power density can be obtained from vertical-cavity surface emitting semiconductor lasers (VCSELs), but the emitting area must be kept small if spatial coherence is desired. We present the result of a theoretical and calculational study of the po

Two versions of the ``Phase-Step Mirror`` (PSM), a novel optical component that prevents the formation of sidebands in a Free-Electron Laser (FEL) were tested on the Los Alamos National Laboratory (LANL) APEX FEL. Sideband suppression and frequency c

An InGaAs/GaAs vertical-cavity surface-emitting laser (VCSEL) with resonant periodic gain (RPG) was optically pumped using a pulsed dye laser at 760 nm with 500 ns pulse width. Output pulse energies at 918 nm in excess of 20 mJ were observed from a 3

The region posterior to the cricoid cartilage is challenging to assess fluoroscopically. The purpose of this investigation is to critically evaluate the posterior cricoid (PC) region on fluoroscopy and describe patterns of common findings. This was a

Pulse Single-Frequency Lasers: Technology and Applications.
A UV wavemeter to determine absolute wavelength to one part in 107 at 308 nm has been fabricated and tested. The wavemeter consists of three fixed-plate, air-spaced Fabry-Perot etalons in an evacuated, thermally stabilized enclosure. The interference

Stable operation of a 1.2 As pulse, high energy, electron beam pumped XeCl laser at a bandwidth of 225 MHz has been achieved. This bandwidth is obtained without external injection by utilizing the self-regenerating feedback from a portion of the broa
