Abstract:
We are now constructing a technical integration experiment line (TIL) at CAEP, which is the prototype facility of Shenguang III laser fusion driver. Currently, many important results have been obtained on the first integrated beam line, which established a sound foundation for Shenguang III engineering design.Keywords:

In contrast to the double event scheme of the fast ignitor, we follow the results of measured high fusion gains to derive single event schemes for laser fusion. Following the results of the volume ignition and the results of low temperature ignition, we report about conditions where a single‐event classical ns laser pulse may be used. Several details were elaborated where the laser compression to more than 3000 times the solid state and with lasers pulses above 5 MJ produce very high gain fusion efficiencies though the initial optimum temperatures are in the range of 500 eV or even less. ‐ Another one‐step laser fusion using the new PW‐ps laser pulses combines the Norreys‐Fews scheme where the effect of a new discovered skin layer interaction is applied under control of prepulses as used for explaining the effect of anomalous low energy of ions emitted from ps irradiated targets measured by Badziak et al.. A drastic increase of the fusion gains for the experiment by Norreys et al. can be expected by application of the interpenetration model discussed earlier for the ANTARES laser.

The present status of laser fusion researches in Japanis described. In the first, the fast ignition laser fusion is the high-light of high power laser applications. The recent progress of fast ignition research project at Osaka University: FIREX will be reported. As the industrial applications of laser produced neutron and X-ray, it is explored how they are used for diagnosing the chemical and physical processes in fuel cell and other chemical energyconverters. These applications are also important topics of this talk. As the laser fusion reactor technology, we will also present "UV Laser Ablations and Erosions to Investigate Fusion Reactor Surface Material Interactions, Hydrogen Storage Thin Layers Formations and the Related Subjects."

For many years, laser-driven fusion has been the realm of large-scale laser science. A number of recent experiments have demonstrated that compact, femtosecond lasers of modest size can also drive nuclear fusion.

Femtosecond laser was employed to induce cell fusion. The interface between two protoplasts of Phaffia rhodozyma in contact was irradiated by femtosecond laser pulses with 1.38×104W for 0.25s. After about 20min, the fusion of cells became visible and finally two cells merged into one larger cell within 160min. Fusion rate at this power level was 80%. The experiments suggested the existence of threshold power for cell fusion induced by femtosecond laser. Regarding femtosecond laser pulses as a trigger, we present a hypothetical model for femtosecond laser-induced cell fusion.
