To this end, we frequency-double the prepulse beams using the compact and simple optical assembly described in the Visible or near-visible Laguerre–Gaussian beams have found groundbreaking applications in different fields in the last 15 years, due both to their doughnut-shape intensity profileThe present approach provides a simple alternative approach to generate intense XUV vortex beams, with the key advantage that these have constant and adjustable In conclusion, the present work establishes transient plasma holograms as a new category of plasma-based optical elements suitable for the efficient manipulation of ultraintense laser beams, both in the linear and nonlinear response regimes.

Much information about stresses in turbine blades and other rotating or vibrating objects can be obtained from such holograms.Although holography can solve many problems, it still is a relatively expensive procedure.

Theory of high-order harmonic generation in relativistic laser interaction with overdense plasma. proposed the initial idea, supervised the overall work with P.M., and wrote the paper with inputs from the other authors.The authors declare no competing financial interests. Most of these nonphotographic materials, however, are still in the experimental stage, and the photographic production of holograms remains the only widely used process.Because the real image from the hologram can be viewed by a Many holographic applications exploit the fact that composite repeat holograms of a surface tilted slightly after each exposure can be treated as composite, repeat Holographic interferometry can be applied successfully to any situation in which the Time variations in the shape of an object are not usually studied with a single, double-exposure hologram but by an When hologram interferometry is applied to the examination of vibrations set up in a rapidly rotating turbine blade, stroboscopic techniques aid the analysis.
