9219450 Diels Our preliminary measurements have shown that the two counterpropgating beams of a ring laser are not coupled in frequency. The implication is that the fs (femtosecond) ring laser is an exceptionally sensitive detector for minute (less than 10-12 m) optical path difference between the counterpropagating beams. Such path difference can be induced by rotation rate), by electro-optic effect (a phase shift of the order of 10-6 can be detected with fs temporal resolution), by motion (Fresnel drag measurements), by magnetic fields (Faraday effect). We propose to explopit these unique properties for various applications, such as detection of small motion, study of the dynamics of ultrafast detectors and circuits, and coherent interactions with 3 level (A of V configuration) systems. We will also apply our understanding of the absence of coupling between counterpropagating modes in the fs dye laser, to develop mode-locked semiconductor ring laser with similar properties. *** j e j ! !

[219450 . Diels]我们的初步测量表明，环形激光的两个反向光束在频率上不耦合。这意味着fs（飞秒）环形激光器是一个非常灵敏的探测器，可以探测到反向传播光束之间的微小光程差（小于10-12米）。这种路径差可以由以下因素引起：旋转速率、电光效应（10-6量级的相移可以用fs时间分辨率检测到）、运动（菲涅耳阻力测量）、磁场（法拉第效应）。我们建议将这些独特的性质用于各种应用，例如小运动的检测，超快探测器和电路的动力学研究，以及与3电平（A / V配置）系统的相干相互作用。我们还将应用我们对fs染料激光器中反传播模式之间缺乏耦合的理解，开发具有类似性质的锁模半导体环形激光器。*** je j!！ F j j (Times New Roman Symbol & Arial " h r 22) 1卡桑德拉·奎恩卡桑德拉·奎恩
