We present the two-photon recording of microholograms in new cationic initiated photopolymer material. The experimental results show that the material has a square-law dependence of the refractive index change on intensity, and also the threshold character of recording. Both such dependence and the threshold character of recording make it possible to improve the microhologram localization at recording and to reduce the crosstalk at reading. Besides that, the use of two-photon absorption increases the homogeneity on depth recording and provides high values of refractive index change Delta n = 3.3 x 10(-3). We also describe the recording/reading of microholograms in ten layers of the designed material, and present data on reading errors and their distribution on depth.
