According to photochemistry theory, the physical processes, in which the plasma flashing destroys the hypo-class band of the high grade structure of the protein molecule and makes the structure of the protein molecule decomposed and extending and relaxing in the crystal hyaline cortex emulsification operation with the Nd:YAG laser, is proposed in this paper. The decomposed products take residual energy and agglomerate each other to form randomly the disordered and desultory structure. Thus the laser-induced delay reaction exiting in the crystal hyaline cortex emulsification operation with the Nd:YAG laser would be explained.
