Standoff detection, identification and tracking of chemical and biological warfare agents is critical to provide hazard warning and dewarning for forces and civilians, and to minimize disruption in deployment of forces. Differential Absorption Lidar(DIAL) can be used for remote sensing of chemical agents via their spectral signatures at MWIR and LWIR wavelengths. However, current gas-laser DIAL systems are not highly robust and cannot access certain critical wavelengths. All-solid-state LWIR lasersystems using optical parametric oscillators (OPOs) are potentially more suitable for field deployment, but have so far been limited by poor electrical-optical efficiencies and by limitations of OPO materials such as AgGaSe2. A further requirement forrapid-tuning and variable bandwidth is also incompatible with conventional mechanically-tuned, fixed bandwidth OPOs. CTI proposes a robust, compact and efficient all-solid-state LWIR and MWIR laser source. The system implements efficient one-micron pumptechnology, enhanced conversion to MWIR, and efficient LWIR generation. A novel non-mechanical scheme provides rapid LWIR wavelength and bandwidth selection. Phase I will demonstrate the spectral control concept in an efficient LWIR OPO. Phase II willdeliver a compact and rugged LWIR OPO. The program leverages CTI's experience in development and productization of MWIR and LWIR OPOs, and in flight qualified solid-state laser systems.Frequency-agile laser transmitters in the MWIR and LWIR are needed forcommercial DIAL sensors for industrial chemical detection, pollution monitoring and leak detection. These lasers are also useful for scientific applications such as high resolution spectroscopy. With minor modifications, SWIR output can be generated as adiagnostic source for WDM communications. High efficiency infrared lasers are also attractive for wind-sensing, free-space communications, search and rescue beacons, IR countermeasures and medicine.
