Latest Patents

One of Xin He's latest patents is a laser fusion welding device. This device includes a 1.9 μm laser light source, a control unit, and a light spot adjusting device. The control unit is designed to manage the laser light source and the light spot adjusting device to modify the laser power density at the object undergoing fusion welding. The 1.9 μm laser light source has an output power ranging from 100 to 500 W. The control unit comprises a time control unit, a power control unit, and a light spot control unit. The time control unit regulates the turn-on time of the laser light source, while the power control unit manages the output power. The light spot control unit adjusts the size of the light spot at the object being welded.

Another significant patent is a method for measuring concentrations of multiple gases using infrared band laser light. This method involves pumping Ho crystal with a 1.9 μm single thulium-doped solid-state laser to produce a 2 μm band near-infrared laser output. The process includes controlling the light-emitting angle of the 2 μm band laser light and measuring the concentration of methane gas in a designated measurement cell. Additionally, the method generates and introduces mid-infrared and far-infrared laser light into other measurement cells to assess concentrations of ammonia, carbon monoxide, carbon dioxide, acetylene, ethylene, and ethane gases.
