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.

Abstract: Disclosed is an improved structure for a fragile plate packaging and protection device, comprising: a box main body provided with an accommodating space, a bottom plate, two first fixing elements, two second fixing elements, and a plurality of buffer elements having gaps. Wherein, said bottom plate is provided in said accommodating space of said box main body, and is in contact with a bottom portion of said box main body; said two first fixing elements are provided in said accommodating space of said box main body face-to-face, and are disposed vertically at a bottom portion of said box main body; said two second fixing elements are disposed on said two first fixing elements respectively, thus ensuring better safety protection of said fragile plate in said box main body during transportation.
