    The Laser Doppler Vibrometers (LDVs) have gained increased popularity among researchers and practitioners. However, LDVs suffer from their dependency on the optical properties of the surface and sensitivity to external interference that may be easily controlled in the laboratory environment....

    An optical interferometric method has been used to measure the static surface deformations caused by a point-focused cw laser. Experiments carried out in Plexiglass show that one can guess for defects or inhomogeneities under the surface through the topography of these deformations.

    In this study, we show the effects of the growth of two noninteracting populations of defects in the cavity of a semiconductor laser diode, induced by accelerated lifetesting. The development of one type of defect is considered to give rise to a particular failure mode or mechanism. Using a...

    Thin films of YBa2Cu3O7-δ have been grown in an oxygen atmosphere by pulsed laser deposition using two synchronized lasers, separated by a variable delay (1 μs–10 ms). The ablated fragments from the first laser lead to formation of a blast wave in O2, leaving behind a rarefied...

    Digital Shearography is a laser based inspection method, capable of determining minute surface displacement gradients in response to an applied stress. The non-contacting technique is based on interferometric principles, and produces whole field results. As a result the method has been adapted...
