The present invention discloses a method for preparing a fiber-type step-type laser flyer energy converter based on MEMS technology, comprising the following steps: first, pre-treating the fiber end face, including polishing, cleaning, and drying; then, placing the fiber into a designed mold, sequentially subjecting the fiber end face to a single photolithography (coating, exposure, and development), magnetron sputtering, and degumming to prepare an ablation layer and a heat-insulating layer; then, sequentially subjecting the film obtained by the single photolithography to a secondary photolithography, magnetron sputtering, and degumming to prepare a flyer layer, thereby obtaining a fiber-type step-type laser flyer energy converter. The advantage of the step-type laser flyer energy converter prepared using MEMS technology is that the flyer film is directly plated on the fiber end face, resulting in good repeatability and low cost.

Due to the step-type energy converter, the energy waste of the plasma caused by flyer shearing is effectively reduced, which is conducive to reducing the impact initiation threshold of the fiber-type laser flyer energy converter.
