Paper Abstract
Currently a photothermoplastic medium (PTPM) seems to be rather perspective to fabricate relief-phase diffraction gratings (DGs). The use of a two-layer PTPM comprised a photosensitive semiconductor layer and visualizing thermoplastic layer seems to be appropriate' .ThePTPM is characterized by profitable combination of high values of both photosensitivity (up to lO5lO6 cm/J) and resolution (up to 2000 mm1), with a dry developing process which is fast enough (about 1-5 s). The thinner the thermoplastic layer, the higher the resonant frequency of the PTPM and the wider the recording frequency bandwidth are allowing us to realize high-quality recording of DGs. The DGs' fabrication on PTPM seems to have advantages due to the relief-phase nature of recording process, which is rather convenient for replication of DGs2.
