A dense matrix equalization method for solar laser pulse amplitude is proposed to address the issues of relatively high equalization complexity and high laser power consumption in the current process of solar laser pulse amplitude equalization. Using wavelet transform technology to eliminate noise signals in the pulse amplitude signals of solar lasers; By using signal resampling technology, the original signal is transformed into a signal with a fixed order ratio, and different order components are extracted to grasp the fluctuation characteristics of the pulse amplitude signal; The fluctuation characteristics of the pulse amplitude signal are used as network inputs to achieve pulse amplitude equalization of solar lasers through training. The experimental results show that this method can significantly reduce the complexity and delay of equalization processing, while also reducing the power consumption during the operation of solar lasers.
