    Abstract: An optical resonator supporting two sets of simultaneously co-existent oscillation modes (30 and 31), having polarizations orthogonal to each other. Mode control elements (28 and 29), such as apertures and phase elements, are introduced into the resonator to allow only preferred modes to exist. The placement and orientation of the sets are designed such that the high intensity zones of one set fall on the nodes or low intensity zones of the other set in an interlaced pattern. Thus, in a laser resonator, better utilization of the gain medium (24) is achieved and the beam quality and brightness over multimode lasing are improved. This configuration improves the performance of high Fresnel number resonators, in both pulsed and continuous lasers, for applications such as scribing, drilling, cutting, target designation and rangefinding. An application of the intra-cavity coherent summation of orthogonally polarized modes is described, whereby azimuthally or radially polarized beams may be obtained.

    Abstract: An acousto-optic scanning system, which relies on two counter propagating acoustic waves with the same frequency modulation. This scheme completely suppresses the linear frequency chirp, and thus enables the generation of fast non-linear scans and non-constant linear scans. By changing the phase between the modulating signals, this scheme also provides fast longitudinal scans of the focal point.

    Abstract: Systems and methods for a quantum computing include a plurality of photonic processing stages, a plurality of heralding-free connections, and circuitry configured to regulate photon flow between adjacent stages such that decisions about stage settings or flow between adjacent stages are free of input from a previous stage. Each heralding-free connection is located between adjacent photonic processing stages. Each photonic processing stage includes at least two of an optical switch, a beam splitter, a waveguide or a photon generator. Methods include transmitting or receiving a plurality of photons via a plurality of heralding-free connections, and regulating photon flow between adjacent stages such that decisions about stage settings or flow between adjacent stages are free of input from a previous stage.
