Problems solved by technology

When this method is used, the damage threshold of the detection device must also be considered. Therefore, when measuring high-energy lasers, the overall energy of the laser beam needs to be attenuated, resulting in most of the high-order components being filtered out, resulting in the use of 1 / e 2 Measurement error when energy determines beam width
In addition, the problem of in-situ detection of strong lasers is also a difficult problem. The previous detection methods can only be carried out on a single unit device of the laser, and it is impossible to detect the installed optical system or re-inspect the laser that has been used for a long time.

Description

technical field [0001] The invention relates to an in-situ detection system for the beam quality of a strong laser, belonging to the technical field of laser testing. Background technique [0002] Since the laser was born more than 50 years ago, the key technology that must be solved is: the development of high-energy lasers with excellent performance to produce high-energy beams with high beam quality, and to provide energy for destroying, powering or processing targets. Core; develop a high-precision tracking and aiming system to make the launch telescope always track and aim at the target in flight, and make the spot lock on a fixed part of the target, that is, the laser converges on the aiming target with the minimum spot, maximum power density, and maximum energy concentration. point, thereby effectively destroying or destroying the target. Therefore, for the development, production and application of high-energy lasers, how to quickly, precisely and comprehensively ev...
