Aculight proposes the development of a frequency tunable source suitable for LADAR measurements from compact military platforms. The source will use a fixed frequency diode pumped solid state drive laser and an optical parametric oscillator, tunable from 1.6 to 2.4 microns. Output energies will be over 100 micro-J through the spectral range at pulse rates of 10kHz. The major technical challenge, ...

High pulse energy, high repetition rate, tunable, narrowband sources are needed for optical pumping of mid-infrared gas laser converters. The source needs continuous tunability over the 1-3 micron band to access different overtone bands in various gaseous gain media. Due to the need for diode pumping of the source, efficiency is critical to minimizing diode costs. Our approach is efficient gene ...

A Cartesian, multigrid, Euler solver is investigated for development as a module suitable for the multidisciplinary design optimization (MDO) environment. The ultimate objective is not to improve the Euler solver (it is already a mature code) but rather to augment or replace the linear panel method flow solvers used in the Automated Structural Optimization System (ASTROS) for the purpose of airfr ...

A methodology is proposed for introducing the capability of modeling active MMICs into the industry-standard three dimensional electromagnetic field simulator High Frequency Structure Simulator (HFSS) and Maxwell SI Eminence. The first objective of the proposed work is to evaluate the existing capabilities of HFSS/Eminence for characterizing the passive three dimensional interconnect problems as ...

Currently, most antenna array designs are mechanically steered. However, as demand for higher performance antennas increases, an electronic replacement for the mechanical system becomes necessary. An alternative that may prove to be more cost effective is to use ferrite patch antennas as the elements in the array. The antenna's radiation characteristics are controlled by the direction and magni ...

We propose a unique GaN-Al(sub x)Ga(sub 1-x)N heterojunction based CCD for imaging in the ultraviolet (wavelengths less than 365 nm). Our proposed device will be solid state, TTL compatible and in it's final configuration solar blind. The Phase I program is aimed at establishing the technical feasibility of our device concept. Our proposed CCD is in essence a GaN-AlGaN gated photoconductor with ...

This proposal describes new low cost, low risk semiconductor-based approaches to fuze trigger circuit technology. These innovative approaches build on the promising new technology platform developed by ARIA as part of earlier SBIR research. ARIA's technology platform, initially developed for driving extremely high speed (400 picosecond rise time), high peak current pulses (400A) through laser di ...

A concept for intelligent, multimedia computer-based training systems integrating intelligent agents with eye tracking and speech (ScanEval) is presented as a means of developing training systems that are more responsive, engaging, and motivating to trainees than current systems relying on more traditional user interface and pedagogical sequencing mechanisms. It is argued, based on published rese ...
