Abstract: A laser processing system includes a laser source, an optical splitting unit, a frequency conversion unit and at least one optical mixer. The optical splitting unit is provided to divide light emitted by the laser source into a first light and a second light, and the first light and the second light have the same wavelength range. The frequency conversion unit is provided to convert the second light into a working light. The working light includes a frequency converted light, and the frequency converted light and the second light have different wavelength ranges. The optical mixer is provided to mix the first light with the frequency converted light.
