Abstract:
The report discusses the technical background, design features, hardware, and performance of the stable master oscillator STAMO CO2 Laser System developed under the contract. This laser which operates with a high degree of frequency stability at a power level of 35 watts has been tailored for use as the driver laser for the high-power laser amplifier at the Rome Air Development Center Floyd Facility. The STAMO configuration uses a low-power master oscillator to injection lock a high-power ring oscillator. This configuration achieves the high degree of short-term frequency stability inherent in the small low-power master oscillator at the 35 watt power level. A feedback control loop is used with a hybrid injection-locking technique to achieve reliable long-term closed-loop operation of the system. Heterodyne measurements of the frequency stability of the STAMO have been made and its stability is shown to exceed the design requirements.
