Grating Formation

Generation of spatial subharmonic gratings in photorefractive crystal under an external AC field and a phase modulated interference pattern is investigated. This method of grating formation can lower the threshold contrast mth for the subharmonic generation.

SynopsisThe interpretation of optical interference experiments at low light intensities and with independent light sources is discussed. A new experiment on interference between modulated light beams is described briefly, and its significance is indicated. There are two appendices, one a fuller discussion of the conditions under which interference and intensity correlation may be produced, the other a comment on one aspect of Jánossy and Nagy's discussion (1956) of the feasibility of the alternating slit interference experiment.
