A technique is suggested to measure the threshold of two-photon initiated photopolymerization involving a Z-scan of a thin film of sensitive material along the focusing axis of the laser beam. A condition of reaching the threshold when scanning the s

A new technological approach makes fabrication of relief computer-generated focusing elements for IR radiation by use of a dry photopolymer recording material possible. The formation of a relief structure by self-development takes place in the dark,

A theoretical model of a new electronically switchable grating design that uses a multilayer structure of an electro-optic (EO) material with an interdigitated-electrode type of array is proposed as an original technique for calculating the induced r

It is demonstrated experimentally that an efficient alignment of a reactive liquid crystal (LC) mesogen is achievable by employing a relief diffraction grating having a pitch smaller than the correlation length of the LC mesogen. Full alignment of th

Reactive liquid crystal (LC) mesogen (trade mark C6M of Merck) is shown to possess efficient relief formation properties. Photosensitive formulation was made by mixing of the reactive LC mesogen C6M with 2% of photoinitiator (Irgacure 651). Photosens

Holographic polymer dispersed liquid crystal (H-PDLC) material was recently sensitized that is sensitive in the near infrared (800 nm to 855 nm). The compound was based on mixture of an acrylate monomer and liquid crystals (e.g., E7 and MBBA were inv
