R. Br, of Zurich, carried out extensive investigations regarding the nature of the phenomenon; he obtained numerous beautiful results concerning the manner in which the relative intensities of the various diffraction spectra depend on the wave-length of light, the supersonic intensity and the ...
We have now observed for this small sound wave-length that, when the sound intensity is slowly increased, the number of these maxima diminishes. Further, the emphasis appears to shift towards the first Bragg angle, instead of the diffraction order attaining the maximum intensity at its respective...

展开 摘要: The effect of space charge waves (SCWs) on diffraction of light is studied. Characteristics of diffraction of light by SCWs and acoustic waves are compared and the efficiency of diffraction by SCWs is demonstrated. 展开 被引量: 1 年份: 1996 收藏...
A theoretical study is made of the diffraction of light waves by dynamic grating structures formed as a result of one-photon absorption of the recording radiation in the waveguide material. The characteristics of diffraction in waveguides with step and exponential refractive index profiles are considere...
