Latest Patents

One of Shan Qiao's latest patents involves a novel laser design. This invention includes a medium with a ground state, an intermediate state, and an excited state in ascending order of energy. The excitation system is configured to excite electrons in the medium from the ground state to the intermediate state. An excitation laser drives electrons in the intermediate state at different spatial positions in the medium to the ground state through a stimulated emission process, generating a laser with a shorter relative wavelength. This design not only simplifies the structure of the short-wavelength laser but also reduces costs while achieving a more compact implementation.

Another significant patent by Shan Qiao is related to an undulator. This undulator comprises at least M permanent magnet periods arranged sequentially in the transmission direction of electron beams. Each permanent magnet period consists of four rows of permanent magnet structures, capable of forming composite magnetic fields through relative displacement. This innovative design allows for the generation of elliptically polarized light, circularly polarized light, or linearly polarized light with an arbitrary polarization angle when electron beams pass through the composite magnetic fields.
