摘要
激光陀螺的关键技术之一是如何减小输出特性中的闭锁阈值。为了提高产品的精度,同时,也为了研制微型产品,有必要研究和应用超短脉冲环形激光技术。在这一方面,作者和美国新墨西哥大学的同行曾进行了研究,并取得了多项有价值的实验成果。近20年来,在地球物理学和地震学的研究中,建成了6台巨型脉冲环形激光装置,它们被成功地应用于精密角速度测量。测试结果表明,在这些装置的输出特性中,闭锁阈值被减小到接近于零的水平,和现有的激光陀螺产品相比较,它们测量角速度的稳定性和分辨率提高了3~5个数量级。
One of the key techniques in ring laser gyro is to reduce the lock-in threshold in its output characteristic. In order to improve the performance in one hand, and to create the miniaturized product on the other hand, it is necessary to investigate and apply the ultra-short pulse ring laser technique. In this aspect, the author has co-operated with colleagues of the University of New Mexico, USA and obtained several valuable experimental results. In the recent two decades, 6 large ring laser apparatuses for rotation sensing have been built,they are operating successfully. In these apparatuses, the pulse ring laser technique has found successful application. As shown by test results, their lock-in threshold has been reduced almost to zero, hence their sensing stability and sensitivity have been improved to 3- 5 times in comparison with the present ring laser gyro product.
