The spacing of layers in a sputtered, multilayer structure was rapidly and permanently increased by heating with a nanosecond laser pulse. During laser heating, the Bragg angle decreased and the peak reflectivity increased for diffraction of soft x-ray radiation at 4.4 nm. Measurements were made using a time and space resolving x-ray streak camera detector.
