  • Patent number: 10390709
    Abstract: A system for detecting pressure, acoustic or ultrasound waves within an entity having a surface including the steps of attaching a signal converting material to the surface. The waves are generated by direct ejection from the surface, generation via energy deposition on the surface, generated spontaneously or, generated by directing light energy to the light absorbing target. The absorbing target subsequently generates acoustic pressure waves. The acoustic waves propagate to the surface of the entity and the signal converting material, wherein the acoustic pressure waves create vibrations in the signal converting material; and detecting the waves in the signal converting material with an optical detection system. Information about the absorbing target is obtained by the absorbing target reflecting the waves. The signal converting material can be a gel-like material containing optical elements, a multi-layer patch, or other material.

  • Publication number: 20190099837
    Abstract: The present disclosure relates to a powdered bed fusion additive manufacturing (PBFAM) apparatus. The apparatus uses a container for holding a quantity of powdered material. The container has a bottom wall for supporting the powdered material, wherein the bottom wall is made from the same material as the powdered material. A temperature sensing subsystem is coupled to a portion of the container for detecting a temperature of the container. A laser generates an optical beam directed at the powdered material held by the container for melting the powdered material. A controller receives temperature information from the temperature sensing subsystem and determines an absorptivity of the powdered material based on the temperature information.

  • Patent number: 9192056
    Abstract: A technique for bonding two dissimilar materials includes positioning a second material over a first material at an oblique angle and applying a tamping layer over the second martial. A laser beam is directed at the second material that generates a plasma at the location of impact on the second material. The plasma generates pressure that accelerates a portion of the second material to a very high velocity and towards the first material. The second material impacts the first material causing bonding of the two materials.

  • Patent number: 9172208
    Abstract: An optical source capable of enhanced scaling of pulse energy and brightness utilizes an ensemble of single-aperture fiber lasers as pump sources, with each such fiber laser operating at acceptable pulse energy levels. Beam combining involves stimulated Raman scattering using a Stokes' shifted seed beam, the latter of which is optimized in terms of its temporal and spectral properties. Beams from fiber lasers can thus be combined to attain pulses with peak energies in excess of the fiber laser self-focusing limit of 4 MW while retaining the advantages of a fiber laser system of high average power with good beam quality.
