| Abstract: | A technique is described for obtaining deep spatial modulation of laser beams. A phase modulator at one plane in the beam path can yield amplitude modulation at a later plane with little loss in power. Explicit formulae are derived for the field distributions of the modulated beams, and applications are considered. |
