摘要: A diagnostic means to enable real-time inspection of bonded structures. The disclosed apparatus detects bond failure stress waves on-axis from the front side (beam application side). Pi-box and pi-rail EMAT gauges can be used with the disclosed apparatus. An inductively coupled EMAT may also be employed. An improved means to remotely deliver an interrogating laser beam to a surface is provided. The process head may utilize a water column or a water film. The water film process head may include the use of either a single water film or two spaced apart water films. The disclosed apparatus can be used with bonded composite structures, bonded structures using various materials, and to determine the dynamic strength of unbonded solid materials. The apparatus may also be used in other applications that require remote flexible delivery of a localized stress wave to a material and/or diagnosis of the resultant stress waves.

摘要: A method and apparatus for improving the functionality, quality, and usefulness of a beam of coherent energy used in laser shock processing by utilizing an apodizer within the oscillator or amplifier of a laser. The apodizer used may be a phase plate, a serrated aperture, a birefringent beam shaper, an absorbent graded aperture, a reflective graded aperture, or a combination thereof. A method and apparatus for reducing or preventing damage to an oscillator and an amplifier utilizes an apodizer.
