AbstractHighly frequency stable optical oscillators are a critical component in coherent detection systems, such as those utilized in range resolved Doppler imaging ladar and advanced photonic signal processing systems. The deployment of highly coherent master optical oscillators becomes increasingly complex in high vibration environments typical of aircraft and space vehicles. The objective of this SBIR effort is to develop a highly coherent diode laser system, based on active frequency stabilization to spatial-spectral (S2) sensor materials. These S2 sensors, manufactured by our company, provide ultra-narrow (~ 1 kHz ) solid state frequency references that are immune to external vibrations. In Phase I, computer based modeling tools for stabilizing a master oscillator to these S2 sensors were developed and their performance predictions were verified through experimental proof-of-concept demonstrations. During the Phase II effort, we will build and test a prototype, designed to meet specific MDA system needs. Work includes implementation of a digital servo control unit developed during Phase I and long term frequency stability circuit development for improved performance.
