Abstract
Un giróscopo de láser anular que comprende un cuerpo de láser anular que incluye superficies reflectoras las cuales definen trayectoria óptica de bucle cerrado medios para generar y mantener al menos dos modos de desplazamiento resonante primarios que se propagan en sentidos opuestos los cuales se propagan en dicha trayectoria óptica con lo cual las diferencias de frecuencia entre dichos modos primarios son representativas del movimiento angular experimentado por dicho cuerpo de láser anular, medios para generar y mantener al menos un modo de desplazamiento resonante secundario que se propaga en dicha trayectoria y se acopla con al menos uno de dichos modos primarios, con lo cual se eliminan o disminuyen los efectos de sincronización y medios para tratar dichas diferencias de frecuencias entre dichos modos primaros para generar señales representativas de movimiento angular de dicho cuerpo láser anular.
