Abstract

The invention relates to a vacuum controllable high-flux heavy-caliber optical focusing and frequency conversion system and belongs to the technical field of optical focusing and frequency conversion. The vacuum controllable high-flux heavy-caliber optical focusing and frequency conversion system solves the problem that an integral structure of an existing optical focusing and frequency conversion system is not beneficial to on-line replacement. The vacuum controllable high-flux heavy-caliber optical focusing and frequency conversion system comprises a target window unit part, a frequency conversion unit part, a focusing lens unit part and a light beam measuring sampling part, wherein the tail end of the target window unit part is in sealing connection with a shell body at the head end of the frequency conversion unit part through a flange, the tail end of the frequency conversion unit part is in sealing connection with a shell body at the head end of the focusing lens unit part through a flange, the tail end of the focusing lens unit part is in sealing connection with a shell body at the head end of the light beam measuring sampling part through a flange, and an atmosphere chamber is formed by the target window unit part, the frequency conversion unit part and the focusing lens unit part. The mechanical structure is designed into a detachable assembly, and rapid replacement of each composition part and each internal assembly can be achieved by a rapid disassembly mechanism through corresponding hatches formed in the shell bodies. The vacuum controllable high-flux heavy-caliber optical focusing and frequency conversion system is applicable to the heavy-caliber optical focusing and frequency conversion.

Description

technical field [0001] The invention relates to a vacuum controllable high-throughput large-aperture optical focusing and frequency conversion system, which belongs to the technical field of optical focusing and frequency conversion. Background technique [0002] Driven by laser fusion technology, the United States, France, China, Russia and other countries around the world are successively building giant laser installations, such as the National Ignition Facility NIF and the megajoule laser LMJ being built in the United States and France respectively. One of the key unit components of the shooting range photoelectric control system of the Shenguang-III laser device being developed in my country is the vacuum controllable high-throughput large-aperture optical focusing and frequency conversion system. The main functions of this system are to complete frequency conversion and harmonic separation. , focusing transmission, focal spot control, and beam sampling, etc., as an optic...
