TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The essential elements that characterize the performance of a laser gyro are (a) a bidirectional ring laser, (b) a lightweight, efficient instrument (c) a high sensitivity to rotation and (d) a linear response without dead band. To address (c), substantial enhancement has been predicted through large intracavity (normal) dispersion dn/df. The objective of Phase I is to demonstrate experimentally this enhancement, in combination with demonstrating the absence of dead band (d) in a solid state laser. A key element is the realization that it is possible to engineer a mode-locked laser where the pulse envelope velocity is controlled by other parameters than the dispersion. We have demonstrated this property in a mode-locked laser with intracavity Fabry-Perot and with intracavity resonant atomic vapor. This property will be exploited in Phase I by inserting in a ring mode-locked Ti:sapphire laser a Fabry-Perot and a Rubidium cell, to demonstrate simultaneously the enhancement of the gyro sensitivity, the use of a solid state gain medium in a gyro, and the absence of dead band. In Phase II, these results will be implemented in a mode-locked fiber laser gyro, to demonstrate the light and efficient instrument required for space applications.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The result of phase II will be a laser gyro extremely light weight (a laser ring cavity made of a fiber) that can be expanded over a very large perimeter, thus have a very large scale factor, enhanced by resonant interaction ("fast light"). As opposed to the actual He-Ne gyro that has to be dithered by giving it a periodic motion, there will be no mechanical part in this gyro. Further development can transform this device into a linear accelerometer.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
A light weight expandable gyro has application in commercial navigation. Because the fiber laser can be made of very large perimeter, it has applications in monitoring the motion of tectonic plates.
