Abstract:

1. Atomic ionization under intense laser field is a new hot spot in the research of atomic physics. Based on the basic theory of quantum physics, the report deeply analyzes the concept, theory, measurement and existence time and space region of quantum tunneling, from semi-classical ionization Starting from the model, it predicts the electron energy spectrum, the associated momentum spectrum and the degree of ionization of a series of atomic strong field tunneling ionization;

2. Starting from the tunneling problem in the deuterium-tritium reaction, the core physical issues involved in the design of the laser fusion target are discussed. The main progress and challenges in laser fusion ignition research at home and abroad are reviewed.
