摘要： A four-frequency laser gyroscope system having improved accuracy is constructed using a single solid block of low thermal coefficient of expansion material. A four-segment nonplanar propagation path provides a first frequency splitting. A second splitting is provided by a Faraday rotator having a thin slab of rare earth-doped glass positioned within an aperture in a permanent magnet. A narrow angle of incidence is provided for the beams of incident upon the output mirror to prevent cross coupling between beams within the output optics structure. Blocking the gaseous flow path reduces output frequency drift caused by contamininating particles.

摘要： A laser mirror mounting arrangement for a laser formed within a laser body is shown. The mounting arrangement includes a mounting base mounted upon the laser body. A stem is attached to the mounting base to which, in turn, the laser mirror is mounted. The stem has a coefficient of thermal expansion selected to maintain the mirror in a fixed position. This is accomplished by permitting the stem to expand due to thermal expansion in one direction, while the laser body expands due to thermal expansion in the opposite direction.

摘要： A ring laser gyro uses a nonplanar path having at least one plane of mirror symmetry and two pathlength control mirrors in order to reduce scatter variations occurring during the operation of the laser gyro. The mirrors used to produce such path are fixed to an isotropic supporting block having passages therein that define the path segments and the mirrors are moved out or in by the expansion or contraction of the block. The two pathlength control mirrors are disposed diagonally opposite each other on the plane of mirror symmetry, and are placed on substrates whose positions are controllable, each substrate being coupled to means for controlling the positions of the substrates as a function of the pathlength. With such a mirror configuration, the pathlength may be held constant by a suitable control means and the relative movement of the mirrors constrains movement, with respect to the mirrors, of the beams circulating in the path to directions perpendicular to the planes of incidence on the mirrors. This causes the beams to sample substantially the same scatter points, normally present on the mirror surfaces, with substantially the same phase throughout the range of movement of the beams.

摘要： A laser gyro system wherein a plurality of nonplanar ring laser gyros are nested within a common supporting block of material. The nonplanar ring laser gyros have a ring path whose circumscribing volume has a size of the order of the volume of the supporting block, each ring path utilizing a portion of the volume unused by the other. In one embodiment, a cubic block contains two orthogonal tetrahedral ring laser gyros. The two rings intersect and share a common gas envelope. In another embodiment, the supporting block contains two orthohedral ring laser paths.

摘要： An electromagnetic wave ring resonator is disclosed wherein field distribution of electromagnetic waves are spatially rotated about the direction of propagation of such waves in said resonator. With such arrangement the electromagnetic field distribution rotation produces a phase difference between waves of opposite polarization senses, thereby enabling the waves to resonate with different frequencies. In a laser gyroscope the electromagnetic field distribution may be achieved by a catoptric arrangement which reduces the loss, scatter and linear birefringence associated with the ring resonator of the gyroscope.

摘要： A four frequency laser gyroscope system having a rugged and compact output structure for producing output signals representing the frequency differences between counter-circulating wave pairs circulating as two beams within the gyroscope cavity. A partially transmitting dielectric mirror forms both one of the cavity reflectors and the means for extracting a small portion of each beam. The two extracted beams are combined on a beam splitter. Both the transmitted and reflected beams from the output of the beam splitter, each containing waves of all four frequencies, are utilized. Each resultant beam is then polarization discriminated to extract the desired signal content. The entire structure is adapted for rigid mechanical coupling and may be constructed to have a small size.
