Optical gain performance of epitaxially grown para-sexiphenyl films

Optical gain performance of epitaxially-grown nanostructured para-sexiphenyl films is demonstrated to be outstanding. The combination of high structural order and low lattice temperature results in a material system with ultrawide (ca. 1 eV) gain bandwidth and long (ca. 1 ns) gain lifetime (see figure) that allows an optimistic outlook for broadband laser applications.
