The sixth"Shenguang · Zhixing"Forum was held that Professor Shi Yin from the School of Nuclear Science and Technology,University of Science and Technology of China (USTC), gave a presentation titled "Axial Megatesla Magnetic Field Generation for kJ-PW-Class Multi-Beam Laser Facilities".

A progress in phase retrieval algorithms for ultrashort pulse measurement was achieved. The research team proposed a novel Multi-grid Parallel Ptychographic Algorithm (MPPA), significantly enhancing the pulse reconstruction capability of Frequency-Resolved Optical Gating (FROG) technology under complex conditions.

Based on an improved broadband Transient Grating Frequency-Resolved Optical Gating (TG-FROG) technique, a significant progress in single-shot characterization technology for complex synthesized laser pulses was made on SG-II facility.

Researchers developed a pulse segmentation model for the Double-Cone Ignition (DCI) scheme. This model redistributes time-power profiles across individual beamlets to reduce waveform contrast, while maintaining the required near-isentropic compression waveform.

The researchers proposed a method to achieve high-precision, three-dimensional (x, y, t) synchronization of ultrashort pulses at different angles by observing the transient phenomena of the optical Kerr effect.
