Description

technical field [0001] The invention relates to an optical focusing and frequency converting device. Background technique [0002] Inertial Confinement Fusion ICF (Inertial Confinement Fusion) is one of the main ways to realize controllable thermonuclear fusion energy, and it can also be used in national defense, basic scientific research and other fields. Since the advent of lasers in the 1960s, ICF research has made important progress worldwide. The focusing and frequency conversion system is located at the end of the entire laser chain, including a variety of large-caliber optical components and their controls, transmission systems and complex mechanical structures. It is a complex system integrating light, mechanics and electricity, and is the key to the ICF device. one of the units. [0003] At present, in inertial confinement fusion devices, there are problems such as difficult online disassembly and assembly of optical components, complex structures, and high costs,...
