Abstract
Moving gratings is an effective method to improve the diffraction efficiency of dynamic gratings. However there is a sudden drop in the optimum fringe velocity when the fringe modulation is close to unit, which restricts its applications. We experimentally showed that optical bias is an effective method of overcoming this problem. We also found that within a certain range of optical bias, the absolute diffraction efficiency can be higher than that without optical bias, which is not the case when using a stationary grating.
