Fast Laser Pulse Shaping for Molecular Control and CB Detection

We propose the development of a robust laser pulse shaping system (LPSS) for commercialization to the defense, industrial and academic communities for advanced laser processing applications. The LPSS will be used for closed-loop control of molecular reactions and dynamics by coherent electromagnetic fields. In Phase I we will design and assemble breadboard LPSS and demonstrate molecular reaction control by modifying the mass spectrum resulting from the decomposition of dimethylmethyl phosphonate, a simulant for the chemical nerve agent Sarin. We will cleave the methyl group or the methoxy upon demand using the system as a component in a strong field closed-loop photonic reactor consisting of a laser system, the proposed LPSS, TOF mass spectrum analyzer and a control system running adaptive feedback pattern recognition codes. We will identify aspects of the LPSS that require further engineering for mass production. In Phase II we will design and build a prototype commercial system that is compact, economical, and rugged with a standard I/O communication interface. The system will be compatible with portable laser systems and detectors suitable for use in the field. Our self-aligning system will include reliable means for calibration and be operable without maintenance for extended periods.
