Abstract

There is provided a device for reducing laser speckle comprising: a first transparent substrate; a second transparent substrate; an SBG sandwiched between said substrates; and transparent electrodes applied to said substrates. The first substrate is optically coupled to a laser source. The face of the second substrate in contact with the SBG is configured as an array of prismatic elements.
