- Description
- Opportunity Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration or to license to further develop the next generation of laser-based detection methods for rare isotopes. Summary This technology uses a high-finesse, optical cavity and two lasers to detect gaseous species via electromagnetic radiation.� The analyte is introduced in between the highly reflective mirrors of the cavity.� The �pump� laser transitions the analyte into an excited state, while the �probe� laser measures the population of this excited state using cavity ring-down spectroscopy (�CRDS�).� These two measurements combined allow for a direct measurement of the analyte and account for interference from other absorbing� species and spectrometer background fluctuations. Background This technique was developed to detect minute quantities of gaseous species using laser spectroscopy, the most sensitive of which utilizes cavity-enhanced methods; however, the sensitivity of these methods is hindered by variations in background signal measurement.� This invention overcomes this hinderance, as it does not have experimental requirements needed to improve sensitivity, adaptation, and deployment in the field. Technology Description 2-Photon, 2-Color, Cavity Ring-Down Spectroscopy (�2P3C�) requires two light sources, an optical cavity, and a detector.� A gaseous analyte is introduced in between the highly reflective mirrors of the cavity.� The �pump� laser is injected into the cavity and excites the analyte into an elevated quantum state.� The second �probe� laser measures the population of this excited state using CRDS.� The pump is then turned off, and the probe can measure the background of the CRDS signal.� Benefits: This technology increases the sensitivity measurements without the exacting experimental conditions required by conventional laser spectroscopy.� It has the ability to detect ultra-trace species, such as less abundant isotopologues and radioisotopes.� All these benefits could be realized even outside the lab environment� Potential Applications Field-deployable laser spectroscopy Note:� THIS IS NOT A PROCUREMENT.� Interested companies should provide a written statement of interest, which includes the following: 1.�� Company Name and address. 2.�� The name, address, and telephone number of a point of contact. 3.�� A description of corporate expertise and facilities relevant to commercializing this technology. Written responses should be directed to: Lawrence Livermore National Laboratory Innovation and Partnerships Office P.O. Box 808, L-779 Livermore, CA� 94551-0808 Attention:� IL #13644 OR EMAIL - Bono4@llnl.gov
