APPARATUS AND METHOD FOR GENERATING HIGH ORDER HARMONIC X-RAY AND PINHOLE DIFFRACTION INTERFEROMETER USING HIGH ORDER HARMONIC X-RAY

摘要

PURPOSE: An apparatus and a method for generating high order harmonic X-ray, and a pinhole diffraction interferometer using the high order harmonic X-ray are provided to increase industrial utility by simplifying the structure of an interferometer using a micro thin film. CONSTITUTION: A laser beam focusing strength controller(11) controls dimension of energy and beam of a femtosecond laser generated in a high-power femtosecond laser generator(10). A target(20) is filled with argon gas which focuses the femtosecond laser beam to generate high order harmonic X-ray. A gas pressure controller(21) controls the argon gas. The high order harmonic X-ray beam generates single-order harmonic wave under the control of the laser beam focusing strength controller and the gas pressure controller.
