Finally, the photoinitiator ionic free radical and the monomer M are subjected to polymerization reaction to form a photopolymer P, wherein lambda and lambda' are reaction constants.
The following are detailed procedures for preparing the red-sensitive photopolymer:
a. at normal room temperature, a beaker is filled with a proper amount of deionized water, then the beaker is placed into a larger vessel filled with water, the vessel is placed on a multi-head magnetic heating stirrer, a switch is turned on, the temperature is regulated to 60-80 ℃, the rotating speed is set to be 400rad/min, then the weighed polyvinyl alcohol is slowly poured into the beaker, the polyvinyl alcohol is stirred and dissolved for about 1 hour, and polyvinyl alcohol sol with the mass percentage concentration of 10-20 wt% is obtained after the polyvinyl alcohol sol is completely dissolved;
b. weighing a proper amount of acrylamide and N, N ' -methylene bisacrylamide, dissolving the acrylamide and the N, N ' -methylene bisacrylamide in 5ml of deionized water by using a small beaker, putting the small beaker on a stirrer, heating to about 30 ℃, and fully stirring for about 20 minutes to fully dissolve the acrylamide and the N, N ' -methylene bisacrylamide;

The manual smearing method comprises the steps of dripping 2-3ml of sol on a clean glass sheet by using a plastic dropper, then enabling the sol to naturally flow, enabling the sol to be evenly smeared on the surface of the glass sheet, and finally placing the glass sheet into a dark and dry box to be dried for 36-48 hours.
Machine coating is to use a spin coater to coat the dry plate. Firstly, putting a clean optical glass sheet into a spin coater, sucking the sheet, dripping about 3ml of sol on the glass sheet by using a plastic dropper, and then adjusting the rotating speed, wherein the low rotating speed is set to be 400rad/min and the time is 18s, and the high rotating speed is set to be 1400rad/min and the time is 30 s. And taking out the dry plate after coating, and putting the dry plate into a dark dry box for drying for 36-48 hours. After drying, the dry photopolymer film required in the experiment is obtained.

Laser emitted by a laser is expanded by L1, collimated by L2, split by P1 to form object light and reference light, reflected by M1 and M2, converged at one point, and irradiated on a dry plate sample to form interference fringes on the dry plate. FIG. 2 is a diffraction diagram of the holographic dry plate of the red sensitive photopolymer after exposure, wherein the central bright spot is a zero-order diffraction spot, and the two small spots beside the bright spot are first-order diffraction spots.
The sensitive wave band of the material is mainly concentrated on a red light wave band, and the peak wavelength is about 650 nm. As shown in FIG. 3, the absorption peak of the red-sensitive photopolymer reaches 85% in a narrow bandwidth region at 650nm, and according to the photoreaction mechanism of the holographic recording material, the photosensitizer component in the recording medium in the holographic recording process can only absorb photons of a specific photosensitive band to initiate a photochemical reaction.
