Latest Patents
One of Baiquan Tang's latest patents is focused on doubly doped lithium niobate crystals. This invention relates to the field of materials for photorefractive crystals. The composition of these crystals is Li Nb O : Fe , M , where M can be magnesium, indium, or zinc. The invention greatly improves the photorefractive properties of LiNbO crystals, achieving a high diffraction efficiency of more than 68%. It also boasts a fast response speed for photorefraction, which is an order of magnitude faster than iron-doped LiNbO. Additionally, it has a high resistance to optical scattering, making it an excellent candidate for three-dimensional optical storage materials with vast market potential.
Another significant invention by Baiquan Tang is the only-readable three-dimensional optical storage device. This invention consists of a computer, a precise rotary table, a writing laser source, a readout laser source, a spatial filter, a spatial light modulator, lenses, mirrors, photorefractive crystals, and a phase-mismatch adjustor. By utilizing green light (532 nm) for writing and red light (670 nm) for reading, the signal-to-noise ratio is greatly improved. This device addresses the challenge of fixing stored information and enables high-density digital storage with minimal distortion and loss.
