Abstract

PURPOSE:To highten the measuring accuracy by effecting the photographical blackening adacent to at least one capillary of the laser plasma capillary tube installed in the ring resonance device inside and then by reducing the backward dispersing light and reducing the width of lock-in area. CONSTITUTION:Ring laser is consists in the following reflecting mirror 5, 6 and 7 placed respectively in the peak of the triangle and a laser tube 1 installed in a light pathway 12 in light pathway 10, 11 and 12 which are produced among the abovementioned mirrors. According to the layout, the laser tube 1 is composed of a laser tube 13 made of a glass in which a laser plasma capillary tube 2 is penetrated through. At this time, said blackening is effected in tube end 14 and 15 of the tube 2 to decrease light reflection and dispersing and then to reduce the backward light scattering therein. By doing so, the width of lock-in area can be remarkably reduced and that measuring accuracy using laser gyro can be improved.
