Pulse Excited Fiber Gyro.
Abstract
The goal of the research was to study the operation of pulse excited gyros. This objective required several innovations: (1) Conventional gyros are excited cw with radiation of short coherence time. The gyro must be pulse-excited. The reason for pulse excitation derives from the ultimate objective of using squeezed radiation for the improvement of gyro performance. Squeezing requires pulse excitation of high peak intensity. (2) Development of laser sources that are of particularly low noise and that have repetition rates of 1GHz or higher. The high repetition rate is required for the suppression of Guided Acoustic Wave Brillouin Scattering. (3) Study and development of a new orthogonal polarization gyro suitable for injection of squeezed vacuum.
