Abstract: The invention discloses a preparation method of mogroside and a processing device therefor, which relates to the technical field of sweet glycoside preparation. The device includes a collection cabin, a collection pipe, a peeling assembly and a centrifugal separation assembly, wherein the collection cabin is provided with the peeling assembly, the peeling assembly can peel a fresh fructus momordicae, and a peeled pulp enters the collection cabin so that the collection cabin can transport the pulp to the centrifugal separation assembly; the centrifugal separation assembly includes a separation cabin, a disc, a centrifugal cylinder and a filter pipe, wherein the disc is rotatably arranged in the separation cabin, a plurality of the centrifugal cylinders distributed in a circle are fixed at intervals on an outer peripheral side of the disc, the separation cabin being further provided with a liquid injection head corresponding to the centrifugal cylinder.

Abstract: The present invention provides a laser, including: a medium, having a ground state, an intermediate state, and an excited state in ascending order of energy; an excitation system, configured to excite electrons in the medium from the ground state to the intermediate state; and an excitation laser, configured to drive electrons in the intermediate state at different spatial positions in the medium to the ground state through a stimulated emission process with a fixed phase relationship, to generate a laser with a shorter relative wavelength. Due to the use of an excitation laser to drive electrons from the intermediate state, the photons generated by the stimulated emission have coherence, thereby forming a laser.

Abstract: A solar powered flag light includes a fixing module, a solar powered panel module and a lighting module. The fixing module includes a first mounting portion, a second mounting portion, and at least one connection portion. The first mounting portion and the second mounting portion are configured to be disposed on two opposite sides of a flagpole. The at least one connection portion is configured to connect between the first mounting portion and the second mounting portion, such that the first mounting portion and the second mounting portion can clamp the flagpole to fix the solar powered flag light on the flagpole. The solar powered panel module is configured to be disposed on the first mounting portion. The lighting module is configured to be disposed on the second mounting portion.
