Abstract

We demonstrate a new direct method of recording of interference patterns which are stable under high light intensities. The patterns are written on thin glass films containing quantum dots or on metal island films by the interference of two pulsed laser beams. A pulsed dye laser at 584 nm, with a 7 nsec pulse, and pulse intensities of 2-5 MW/cm² produced gratings with a period l depending on the angle, α, between the two beams according to l = λ/2sin(α/2).
