Abstract In this information age, we have focused on the photosensitive materials for the information storage devices. In order to synthesized the photosensitive azo-polymer and studied the surface relief-grating (SRG) fabrication and real time image recording using diode-pumped solid-state (DPSS) laser of 532 nm, and diffraction efficiency (DE) of polymer using low power DPSS laser at 633 nm. But, the DE of synthesized polymer is low even after 15 min exposure. Hence, to increase the efficiency and reduce the time of DE measurements for synthesized polymer, we have investigated the SRG and DE with combination of azo-polymer and ionic liquids (ILs). We have used various ILs such as 1-methylimidazolium chloride ([Mim]Cl) from imidazolium family IL. Diethylammonium dihydrogen phosphate (DEAP), triethylammonium 4-aminotoluene-3-sulfonic acid (TASA) and tributylmethylammonium methyl sulfate (TBMS) from ammonium family ILs. For the first time, we observed that DE has increased dramatically for DEAP-azo-polymer mixture in 4 min as compared to azo-polymer (alone) and other polymer-IL mixtures. Therefore, DEAP IL can help in increasing the efficiency of DE measurements in less time.
