Paper Abstract

We report the optical amplification characteristics of an optical-field-induced-ionization (OFI) Ar2 * excimer vacuum ultraviolet (VUV) amplifier at 126 nm by using two experimental approaches. We have observed the amplification of OFI Ar2 * excimer emission and evaluated the gain length product of 1.0 by using an optical cavity. We also achieved the gain length product of 5.0 by measuring the one pass amplification inside a hollow fiber with the length of 5 cm. The use of a hollow fiber was effective to guide the VUV emission and to extend a gain length. A small signal gain coefficient of 1.0 cm-1 was evaluated in both experimental approaches.
