Interior Noise Reduction for Armored Vehicles

In Phase I CTI demonstrated an innovative, frequency-agile laser source that could tune throughout the midwave infrared spectral region (4-6 um). The source was based on a Cr:ZnSe laser pumping a ZnGeP2 optical parametric oscillator (OPO). Advantages ofthis system include that both the laser and OPO operate well at room-temperature with only passive cooling, the system is amendable to power scaling, and rapid wavelength tuning is possible. OPO slope efficiencies of over 50% were demonstrated.Additionally, the system can produce a variety of waveforms with fine control over both temporal and spectral output characteristics. In Phase II CTI will build a compact, high electrical efficiency device that outputs multiple watts of power at desiredwavelengths. Additionally, the output waveform will be optimized for Navy applications. Lastly, CTI will demonstrate that the device can be engineered to meet end-user platform requirements.
