Abstract:

Studes were conducted on adapting the Sperry ring laser for rotation sensing. The investiga tions were conducted at three different wave lengths-0.6328, 1.153, and 3.39 microns-using the He-Ne gas system. Although higher gain is realized at 3.39 microns and increased sensi tivity at 0.6328 micron, it appears that the 1.153-micron laser is more suitable for ex perimental evaluation because of superior stability. Consequently, the more practical Faraday biasing technique is currently being designed for the 1.153-micron system. Improve ment of an order of magnitude resulted from an alternate optical combiner which inherently reduces energy coupling from one traveling-wave mode to the other. All results are in keeping with the qualitative hole-burning theory and nonlinear oscillation model that is discussed in the report. Author
