Abstract :
Summary form only given. Two-photon exposure can be advantageous for the improving of spatial resolution of an image. Two-photon exposure uses the square of the pulse intensity profile, resulting in decrease of the spot size. More important, it has been shown recently, that multi-frequency beams can interfere with each other to produce a doubling of spatial resolution (although at 2:1 pedestal) if the media exposure is due to two-photon. We performed our experiments using Kodak commercial film.
