Temporal-space transforming pulse-shaping system with “knife edge” apparatus in “Shenguang II” upgrade facility
temporal pulse shaping “knife edge” apparatus quasi-square larger energy laser pulse high temporary filling factor
Abstract
The temporal pulse shaping was realized by using temporal-space transforming pulse-shaping system with the own-designed “Knife edge” apparatus, for the first time to our best knowledge, in a large energy laser facility with the output energy of 454.37J. A quasi- square laser pulse with the pulse width of 1.16ns, the rising time of 337ps, the falling time of 360ps, and the temporal filling factor of 81.2% was obtained. It is quite satisfied with the requirement of physical experiment. In addition, the further improvements of our system have been suggested in order to enhance the stability and the flexibility as well as the restoring ability of the temporal-space transforming process.
