Phase properties of X((2)) gratings in glass
Abstract:
A new method for the measurement of the phase shift between second-harmonic light generated by a bulk glass and the injected second-harmonic seed is presented. A linearly polarized pump and a second-harmonic seed with noncollinear polarizations were used for preparation of cerium-doped lead-silica glass. Independence of the phase shift from the angle between the polarizations of the recording waves is demonstrated, and a phase shift value close to 90 degrees is observed, i.e., the X((2)) grating was in phase with the real ?E(EE)?.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
