The variational two-electron reduced-density matrix (v2RDM) method provides an effective framework for computer modeling of the electronic structure of complex molecules and materials that exhibit strong correlation effects. In Phase I and Phase II of this STTR we have demonstrated that the GPU-accelerated implementation of the v2RDM-based complete active space self-consistent field (v2RDM-CASSCF) ...

To meet the U.S. military needs for hardened laser-ranging sensors for munitions applications, a compact, high-repetition-rate, high-pulse-energy laser rangefinder will be developed consisting of a temperature-stabilized avalanche photodiode (APD) receiver, with a few photons equivalent sensitivity, and a miniature diode-pumped microchip laser. An existing integrated circuit design will be updated ...

The objective of this Phase II proposal is to continue the development of a Photoconductive Semiconductor Switch (PCSS) with an integrated optical trigger that can switch at least 30 kV, 1 kA, 20 ns pulses with jitter 108 shots. Ness Engineering, Inc. (NEI) and Texas Tech University (TTU) propose to utilize wide bandgap materials to demonstrate lock-on switching and allow much less optical trigger ...

Variational two-electron reduced-density-matrix (v2RDM) methods can provide a reference-independent description of the electronic structure of many-electron systems that naturally captures multireference correlation effects. These methods offer one of the few possible routes to performing the large-active-space computations that are necessary for the qualitative description of strongly-correlated ...

In response to the Army STTR Topic A14A-T015 solicitation for tunable high-power LWIR lasers for standoff detection applications, Pranalytica proposed to develop a compact, rugged and highly reliable wavelength tunable quantum cascade laser (QCL) module delivering over 5W of peak power and over 0.5W of average power in the spectral region spanning from 7 to 11m. The proposed approach is based on a ...

Cornerstone Research Group, Inc. (CRG) has developed a solid Ceramic Polymer Composite Electrolyte (CPCE) for metal-air power sources. The existing electrolyte solutions favor ionic conductivity at the sacrifice of mechanical performance resulting in metal-air batteries that are fragile and unpractical for portable applications. In Phase I, CRG developed a solid CPCE by combining superionic conduc ...

This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...

This program creates a new class of advanced transceiver techology. This technology can create 40 Gbps VCSEL-based micro-transceiver (uTRX) components that operate reliably over the standard military temperature range of -55°C to 125°C in Army environments. uTRXs are low-cost, compact components that can be assembled onto the PCB in close proximity to high-performance ASICs using conventional ...

Many military applications require efficient optical sources producing several to hundred watts in continuous-wave (CW) or quasi-continuous-wave (QCW) operation at room temperature (RT) in the MWIR (3-5 micron) and LWIR (8-12 micron) regions. While QCLs have become the sources of choice in these spectral regions, the only realistic option to attain hundred-watt power level with good beam quality i ...

Current of the shelf commercial laser systems that are used for LIBS and other optical detection techniques are too costly, large, low performance and unreliable. The reason for it is because commercial laser systems are designed for continuous operation. Only one or few laser pulses are needed for detection, therefore, low cost burst lasers with the proper parameters are needed. Burst mode operat ...
