“…Currently, the shaping of laser pulses is realized using a trigger signal, whose shape is iteratively modified until the required laser pulse shape is obtained [8] . A series of experiments were carried out on the Shenguang III prototype laser facility, such as studies on implosion and ablation, which need various stepped pulse shapes, and the capability of laser pulse shaping technology was proven [9,10] .…”

An X-ray radiation source with approximately constant radiation temperature is realized by irradiating golden hohlraum with a shaped laser pulse. A simple theoretical model based on power balance is used to design the shape of the drive laser pulse. Experiments are carried out on the Shenguang III prototype laser facility, and the experimental results are presented for radiation sources with the flat-top lasting about 2.5 ns at two different peak temperatures of about 150 eV and 170 eV, respectively, including the time histories of the temperatures, the shapes of the drive laser pulses and the time integrated radiation spectra. The validity of the model and possible improvements are discussed.

“…With the progress of the construction and the physics experiment, it is more and more urgent to test SG-III's capability of generating complex laser pulse shapes as well as to demonstrate the correctness of the technical pathways of the front-end system. There has been early work in generating shaped laser pulses in previous laser facilities, such as the SG-II laser facility [12,13] and the SG-III prototype [14] . In this Letter, we report the latest pulse shaping experiment results in the SG-III laser facility.…”

The generation and measurement of complex ultraviolet laser pulse shapes is demonstrated in the SG-III laser facility. Relatively high contrast ratio of 300∶1 required by the physics experiment is achieved and successfully measured. Two continuous main shots validate the reproduction and the stability of the pulse shape, which provide solid foundation for precise physics experiment and laser power balance.

In the process of laser pulse transmission, amplification and sampling measurement, the amplitude-to-frequency modulation (FM-to-AM) effect caused by spectral distortion leads to peak oscillation of waveform measurement data, which is difficult to be completely eliminated by improving measurement methods. In this paper, a method of removing the FM-to AM effect of pulse waveform data based on deep learning is proposed. After the original waveform data is de-modulated, the accuracy of waveform prediction is obviously improved. This technology can precisely remove modulated signals while retaining the key features of original data, and can well deal with various complex waveform data.
