Problems solved by technology

[0003] This scheme is applied to the collimation and energy measurement of large-aperture beams. The technology based on near-field sampling requires the use of large-aperture imaging lenses, which makes the entire optical path long and large in size; The baffle can be moved in and out, and the baffle can be closed before high-energy shooting to protect the near-field detector and far-field detector, making the device complex and expensive

Abstract

The invention relates to a large-aperture light beam collimating and measuring device based on far-field sampling. The collimating and measuring device comprises a small hole of a space filter, a first space filter lens, a second space filter lens, a first light leakage reflector, a beam compressing lens, a near-field imaging system composed of a near-field imaging lens and a near-field detector, and a far-field imaging system composed of a far-field imaging lens and a far-field detector; the output end of the near-field detector and the output end of the far-field detector are connected with a computer; the computer is connected with a collimation adjusting motor reflector group; and the collimation adjusting motor reflector group is composed of a first motor reflector and a second motor reflector. The collimating and measuring device is characterized by also comprising a wedge plate, a rectangular prism, a total reflective mirror and an energy meter assembled on a guide rail. The large-aperture light beam collimating and measuring device is characterized by simple devices, easy adjustment, small size, low cost, and capabilities of collimation and energy measurement.

Description

technical field [0001] The invention relates to a high-power laser device, in particular to a large-aperture beam collimation measurement device based on far-field sampling in the high-power laser device. Background technique [0002] The current high-power laser devices used for inertial confinement nuclear fusion at home and abroad, such as the Shenguang П device in my country and the NIF device in the United States, all involve the collimation adjustment and energy measurement unit of the large-aperture beam. The traditional large-aperture beam collimation measurement device is based on near-field sampling, and its optical path structure is as follows: figure 1 shown. The traditional large-aperture beam collimation adjustment technology adopts the establishment of a near-field imaging lens 7, a near-field movable in and out baffle 13, and a near-field detector 8 behind the transmitted light path of the second motor reflector 12. Monitoring system, and set up a far-field...
