    摘要: Apparatus and methods for modulating light involving the formation of bubbles in a normally opaque dye solution contained within a cell. The bubbles are created in the dye solution by focusing a beam from a laser in regions of the dye solution thereby vaporizing a solvent in the solution. When the bubble is formed, the modulator becomes substantially transparent in the region of the bubble. If the focused laser beam is turned off, the bubble condenses and the modulator again becomes opaque in the region of the condensed bubble.
