The development of laser standoff detection systems for toxic gases is proposed. The systems will use new broadly tunable distributed feedback (DFB) lasers operating in the mid-infrared spectral region. The laser technology has already demonstrated a capability for significant wavelength tuning. The Phase I effort will focus on modeling the laser performance with the objective of extending the laser tuning range. A design will be developed for DFB lasers to be fabricated in Phase II. A standoff detection DIAL system will also be designed in Phase I to be used in a Phase II technology demonstration, targeting the remote measurement of selected toxic gases.
