The objective of the project is to develop a Mid IR Semiconductor Laser Assembly (MIR/SLA) that can be used as a compact reliable "hands-off" transmitter for Laser-Based sensors. A Mid IR Semiconductor diode laser, fabricated to operate in the 3.3 to 3.5 micron region, will be integrated with a Stirling Cycle Cryocooler, and an External Cavity Tuner to yield a minimum of two laser wavelengths. The latter are the basis for Differential Absorption Lidar (DIAL) to carry out remote detection of the target species, such as low weight alkanes. The External Cavity Tuner will be designed so that it can be operated electronically in a true "hands-off" manner. The design of the total package will be geared to rugged, reliable operation that lends itself to low cost manufacture. A breadboard of the design approach will be assembled and tested to verify concept feasibility.
