The application discloses a multi-adaptive quick-release plug, relates to the technical field of packaging material auxiliary tools and pipe end plugging, and comprises a pair of three-inch plugging pieces and six-inch plugging pieces which are assembled with each other and installed in corresponding paper cores. The three-inch plugging piece comprises a three-inch plug which is plugged at the end of a three-inch paper core, and a circle of three-inch supporting plates is fixedly installed at the end of the three-inch plug. The six-inch plugging piece comprises a six-inch plug which is plugged at the end of a six-inch paper core, and a circle of six-inch supporting plates is fixedly installed at the end of the six-inch plug. An extrusion plate is fixedly installed on the inner wall of each six-inch supporting plate. When the three-inch plugging piece is installed in the six-inch plugging piece, the three-inch supporting plates will be in extrusion contact with the extrusion plates, push the six-inch supporting plates to expand outward, and extrude the three-inch supporting plates to shrink inward. The multi-adaptive quick-release plug disclosed by the application has the effects of being multifunctional, high in strength and stability.

The application discloses application of two-dimensional transition metal boride in a saturable absorber and a laser, and the two-dimensional transition metal boride is Mo 4 / 3 B 2‑x T z The application builds a fiber laser based on two-dimensional Mo 4 / 3 B 2‑x T z , optimizes Mo 4 / 3 B 2‑ x T z saturable absorber and a cavity structure of the fiber laser, and after adjusting pump power and a polarization state in the cavity, self-starting of ultrashort and high-repetition-rate mode-locked pulses is realized.
