A Numerical Study of the Nanosecond and Subnanosecond Performance of GEKKO XII-Module

摘要

A numerical study is conducted to examine the performance potential of the GEKKO XII-Module, a phosphate glass laser system currently under development at Osaka University. The study shows that with appropriate modifications, this system should produce peak powers up to 3.6 TW/beam in a 50 psec pulse, and 2-2.5 kJ/beam in a 1 nsec pulse. The similarity between the GEKKO XII-Module and Shiva beam line configurations suggests that a phosphate glass retrofit of Shiva could produce nanosecond pulse energies up to 50kJ. (Author)
