Currently large capacity cryostats, capable of hosting experiments for many qubits, require expensive and hard to obtain liquid cryogens. A few small cryo-free systems exist but they are non-ideal for this use. An opportunity exists for a large scale, c

An eye-safe optically pumped laser based on a gas-filled hollow optical fiber will be demonstrated to lase at both near infrared (IR) and mid IR wavelengths. These lasers will be the first in a new class of IR lasers, based on the combination of hollow-f

Two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. In Phase I, New Span Opto-Technology has demonstrated novel concepts of both holographic recording technique and recording material system without the use of high voltage. We have ...

The objectives of this Phase-II research effort is focused on transitioning noninvasive diagnostic techniques based on ultrafast lasers for characterizing nanoenergetic materials and their performance in rocket engine environments. Through the use of ultrafast laser imaging and spectroscopy, it is possible to isolate and characterize each physical process from initiation through energy release an ...

While DNS of complex flow phenomena is a routine practice nowadays, the analysis tools lack the sophistication to utilize the abundance of data generated, for they are devoid of physics-based data extraction and feature-detection protocols. The current effort proposes an automated and intelligent co-processing data-mining framework, in the form of an API, that detects and tracks flow features of s ...

Having recently built a 32-beam micromachining workstation, a systematic investigation that rigorously quantifies the multifocal, micromachining approach will be performed. While the manufacturing throughput gains of a multifocal approach are obvious, the method needs to be thoroughly characterized to identify the conditions that produce the features of highest integrity at the highest manufacturi ...

RNET Technologies, Inc., (RNET), a small business located in Dayton, OH, is responding to the STTR in collaboration with Prof. Bradley Duncan and Prof. Joe Haus of the University of Dayton (UD). The solicitation states that the objective of this STTR is to develop sub-aperture based EO imaging systems capable of being near conformal and of compensating for atmospheric effects. It also states that ...

We propose to develop a fully electro-optic beamsteerer for large aperture beams. The beamsteerer will be able to deflect 3-cm beam into a field of regard of 50 deg x 20 deg. In Phase I we will demonstrate and model key technologies needed for a Phase II deliverable. These include a highly birefringent liquid crystals, waveguide couplers, and high-index, high contrast waveguides that will give ...

In this STTR program, CFDRC, in collaboration with the University of Idaho, proposes to develop some novel high-performance polynitrogen energetic materials for propellant applications. The proposed materials contain amine substituted tetrazole-based heterocyclic cations. In order to enhance the energy content and stability further, they are combined with energetic anions. These anions will have ...

The design of future hypersonic vehicles requires detailed understanding of flow regimes ranging from rarefied to continuum. Moreover, hypervelocity flows are characterized by high temperatures, excitation of vibrational level of molecules, nonequilibrium dissociation, and ionization. The goal of this project is to develop unified kinetic/continuum solution methods with proper domain decompositio ...
