Patent Number: 
Section: claims

1. An ultraviolet laser sterilization system comprises:an ultraviolet laser module emitting an ultraviolet laser light with a wavelength ranging from 200 nm to 280 nm, the ultraviolet laser light irradiating an area ranging from 1 mm2 to 4 mm2 and having a light intensity of 5 kilowatts (KW) peak power; anda scanning module including a plurality of reflectors for receiving the ultraviolet laser light, and a controller for controlling rotation of the reflectors to adjust an angle of emergence of the ultraviolet laser light for sterilizing a target. 2. The ultraviolet laser sterilization system as claimed in claim 1, wherein the wavelength of the ultraviolet laser light is 266 nm. 3. The ultraviolet laser sterilization system as claimed in claim 1, wherein the system is further provided with an ozone detector module electrically connecting to the controller for transmitting a signal of ozone concentration detected in the environment to the controller, so as to allow the controller to adjust the power and the irradiation time of the ultraviolet laser light on a target.
