Abstract

L'INVENTION CONCERNE LES LASERS A ANNEAU. ELLE SE RAPPORTE A UN LASER A ANNEAU DONT LE FAISCEAU A UN TRAJET SENSIBLEMENT CARRE, ET LA LONGUEUR DU TRAJET EST REGLABLE PAR DEPLACEMENT EN TRANSLATION D'UN MIROIR CONCAVE, UN AUTRE DES MIROIRS ETANT LEGEREMENT INCLINE. APPLICATION AUX GYROSCOPES A LASERS A ANNEAU.THE INVENTION RELATES TO RING LASERS. IT RELATES TO A RING LASER WHOSE BEAM HAS A SENSITIVELY SQUARE PATH, AND THE LENGTH OF THE PATH IS ADJUSTABLE BY TRANSLATION OF A CONCAVE MIRROR, ANOTHER OF THE MIRRORS BEING SLIGHTLY INCLINED. APPLICATION TO RING LASER GYROSCOPES.
