Abstract

Optical-field-induced ionization (OFI) electrons were produced in a 30 cm Ar-filled hollow fiber by shining a high-intensity laser into the fiber. By use of such a long plasma with the help of a multilayer dielectric mirror made for 126 nm emission, we observed significant optical amplification of the Ar2* emission at 126 nm. The optical amplification resulted in a maximum small signal gain coefficient of 0.16 cm-1 at 126 nm at 10 atm of Ar pressure.
