Latest Patents

Xiaoyan Liang holds a patent for a novel laser design. The invention provides a laser that 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 with a fixed phase relationship. This process generates a laser with a shorter relative wavelength. The use of an excitation laser to drive electrons from the intermediate state ensures that the photons generated by the stimulated emission have coherence, thereby forming a laser. The invention combines primary pumping with an excitation laser performing secondary pumping to generate lasers with a relatively short wavelength. The structure of this short-wavelength laser is simple, compact, and easy to implement. Additionally, the cost of producing the short-wavelength laser is reduced, making it a valuable advancement in laser technology.
