High-energy pulse laser multi-path measuring device and method

Abstract

The invention relates to a high-energy pulse laser multi-path measuring device and method. According to the high-energy pulse laser multi-path measuring device and method, a first darkroom and a second darkroom are built. The first darkroom is used for performing attenuation and light split processing on incident beam, and the processed beam enters the second darkroom through a light through hole of the first darkroom. The second darkroom provided with a beam collecting device is used for collecting the beam from the first darkroom. An output module is used for outputting beam collecting results from the second darkroom. A first parallel light attenuation module, a second parallel light attenuation module and a synchronous control device are arranged in the first darkroom. The synchronous control device generates synchronous control signals on the basis of reflected light generated by the fact that the first parallel light attenuation module performs attenuation on the incident beam and controls the beam collecting device located in the second darkroom to perform beam collection on corresponding parallel beam meanwhile. The high-energy pulse laser multi-path measuring device is suitable for measurement of high-energy pulse laser, and meanwhile can be used for measuring low-energy and continuous laser.

Description

technical field [0001] The invention relates to a near-field laser measurement device and method supporting multi-channel synchronous measurement, belonging to the technical field of laser measurement. Background technique [0002] With the development of science and technology, high-energy pulsed lasers have been more and more widely used in scientific research and industrial production, such as: fast response dynamics, spectral analysis, medicine and other fields. At present, the application degree of laser technology has become one of the symbols to measure the advanced nature of a country's industrial technology, and the quality of laser has a decisive effect on the application range and depth of laser technology. [0003] The measurement and evaluation of beam quality is one of the important aspects of laser research. In order to meet the needs of different users, various parameters need to be measured for the beam emitted by the laser light source. However, most of t...

Problems solved by technology

The method of removing the background by software essentially reduces the dynamic range and accuracy of the measurement; for the solid-state laser pumped by the flash lamp, the emission spectrum of the pump light is a continuous spectrum with a wide range, and the attenuation effect of the attenuation system on the scattered ambient light is not obvious.
