Abstract

The invention relates to the technical field of preparation processes of special parts for laser fusion ignition, in particular to a femtosecond laser processing method and system for a polymer spherical crown in double-cone collision ignition. The specific process comprises the following steps of depositing and growing a layer of polymer film on a micro steel ball on a steel mesh substrate; positioning machine vision focus on the surface of a micro steel ball film through a mobile platform; integrally cutting off a spherical crown thin film from the micro steel ball; stripping the cut spherical crown thin film from the micro steel ball through light wiping of a cotton swab; and flatly placing the stripped spherical crown thin film on a glass slide, and modifying and processing the edge of the spherical crown by using femtosecond laser. On the premise that the machining size is guaranteed, high-quality machining of the spherical crown film of a double-cone target is achieved, and the quality of the spherical crown meets the precise matching requirement of the double-cone target. A screening standard is provided for spherical crown processing, a reliable technical route is formed, the high consumption requirement of a spherical crown sample in an ignition test is guaranteed, and development and research of laser controllable nuclear fusion are promoted.

Description

technical field [0001] The invention relates to the technical field of preparation technology of special components for laser fusion ignition, in particular to a femtosecond laser processing method and system for polymer spherical caps in double-cone collision ignition. Background technique [0002] Laser controllable nuclear fusion is expected to completely solve the energy problem, and it is a research direction that the United States, Europe, Japan and other countries are investing heavily in. The realization of laser fusion requires not only a deep understanding of its inherent complex physical processes, but also a comprehensive breakthrough in engineering capabilities. Academician Zhang Jie of the Chinese Academy of Sciences proposed a double-cone collision laser ignition scheme, which provided a new idea for laser fusion research. In bicone collision ignition, light cone irradiation is used instead of spherical irradiation, and the ignition target is changed from a t...
