Optical fibre gas laser and optical fiber type ring laser gyroscope possessing the laser

Abstract

This invention provides a fiber gas laser and a fiber ring laser gyro with said laser, in which, the fiber gas laser includes exciting gas, optical resonance cavity and an exciting source characterizing that said cavity is composed of hollow fiber and a single-mode fiber coupler, two arms of the coupler are solid fibers and connected with two ends of the hollow fiber separately, and exciting gas as gain medium is filled in the core of the hollow fiber. 本发明提供了一种光纤气体激光器和具有该激光器的光纤型环形激光陀螺仪。该光纤气体激光器包括激励气体、光学共振腔和激励源，其特征在于，该光学共振腔由空心光纤和单模光纤耦合器构成，所述单模光纤耦合器两臂为实心光纤，所述两臂分别和所述空心光纤的两端相连接，所述空心光纤的纤芯中充满作为增益介质的激励气体；结构简单，成本低廉，尺寸可调，放大性能好。由此气体激光器制成的光纤型环形激光陀螺仪可以应用于机器人系统、汽车导向系统等多个领域。
