Abstract: Embodiments of systems and methods for fluid or structure surface disinfection using a series of pulsed lasers are disclosed. In an example, a system for fluid or structure surface disinfection includes a laser source, an optical module, and a controller coupled to the optical module. The laser source is configured to generate a laser stream. The optical module is configured to shape the laser stream and direct the laser stream toward a portion of a surface of a structure. The controller is coupled to the optical module and configured to control the optical module to direct the laser stream toward the portion of the surface of the structure.

Abstract: An optical amplification system that includes a combiner and an active fiber. The combiner is configured to receive and combine an input signal and an excitation signal. The active fiber is configured to receive the input signal and the excitation signal from the combiner and generate an amplified input signal. The active fiber is directly coupled to the combiner.

Abstract: Disclosed is oleaginous yeast and its application, belonging to the technical field of microorganisms. The oleaginous yeast provided by the disclosure has been deposited in China Center for Type Culture Collection on May 21, 2020, with an accession number of CCTCC NO: M 2020139. The oleaginous yeast provided by the disclosure can use a hydrolysate of cheap lignocellulose biomass as the substrate. Xylose and glucose in the hydrolysate are simultaneously utilized to produce oil, so the sugar utilization efficiency and production intensity are enhanced. After 8 days of fed-batch fermentation, the oil yield can reach 31.33 g/L, and the oil content can reach 60.83%. The waste resources can be reutilized, and the production cost is reduced, so the oleaginous yeast has wide application prospects.

Abstract: Embodiments of systems and methods for medical treatment using a series of pulsed lasers are disclosed. In an example, a system for medical treatment includes a laser source, an optical module, and a controller coupled to the optical module. The laser source is configured to generate a series of pulsed lasers. The optical module is configured to provide a series of focused laser spots on a patient based on the series of pulsed lasers. The controller is configured to control the at least one of the optical module and a stage for holding the patient to move the series of focused laser spots on the patient to form a scan pattern.
