    摘要： A laser peening apparatus is available for laser peening a hidden surface of a workpiece, the hidden surface not being line-of-sight accessible to laser energy for treatment thereof. The apparatus includes a pulsed laser system and a laser directing unit. The pulsed laser system is configured for generating the laser energy used for laser peening. The laser directing unit operatively receives and channels the laser energy generated by the pulsed laser system. The laser directing unit includes a laser transmission end and is capable of variably and selectively positioning that laser transmission end. The laser directing unit is thereby configured for variably and selectively directing laser energy upon the hidden surface via the laser transmission end.

    摘要： A laser amplifier for laser shock processing having a pump cavity supplying photons at selected or variable wavelengths and orientations to that of the gain medium present therein. In one embodiment, the pump wavelength is substantially equal to a corresponding wavelength difference between the upper laser state energy level and the ground state energy level of atoms composing the gain medium. In an alternate embodiment, photonic energy is applied asymmetrically to the gain medium to produce a desired spatial energy profile. The pump cavity may comprise an alexandrite laser or a diode laser system. Depending on the type of pump cavity, the photonic energy is applied to the gain medium either longitudinally or transverse to the laser beam axis of traversing therein.

    摘要： A technique for increasing the lifetime of optical components that are used in a laser for laser shock peening. The technique employs a properly sized iris or a gradient reflector within a laser oscillator to produce a single-transverse-mode laser beam. This technique eliminates hot spots that significantly reduce the lifetime of optical components. Utilization of the present invention can increase the lifetime of components by a factor of ten of their conventional lifetime.

    摘要： A radar transducer has a planar array antenna mounted on a plate portion of a housing with the microwave transceiver mounted on the opposite side of the plate and carrying a PCB defining the processing section for supplying an output to a cable. The plate portion slides into a plastic receptacle defining the radome for the antenna with a potting compound sealing the open face of the receptacle. The electrical processing section is shielded from extraneous electromagnetic waves without additional metallic shielding elements. The processor is programmable in response to signals received through the output cable so as to re-configure the program thereof so as to change the output to the output cable for different end use controllers and for compatibility with communications protocols. The processor is programmed to carry out a test of the operation of the transceiver and to provide a failure output signal to the cable in the event that the operation is found to be outside predetermined parameters.

    摘要： A system for evaluating the integrity of a bonded joint in an article includes a laser configured in a laser shock processing arrangement to perform a laser shock processing treatment on the article. A beam delivery system employs an articulated arm assembly to communicate the radiant energy emitted by the laser to a process head proximate the article. The laser shock processing treatment causes the formation of shockwaves that propagate through the article, inducing internal stress wave activity that characteristically interacts with the bonded joint. A sensor detects a stress wave signature emanating from the article, which is indicative of the integrity of the bond. A detector such as a non-contact electromagnetic acoustic transducer provides a measure of the stress wave signature in the form of surface motion measurements.
