Abstract
A fluid filled fiber for a quasi-phase matched generator and a laser incorporating such a fluid filled fiber. The liquid filled fiber has charge transfer molecules dissolved in a solvent. In another embodiment, the liquid of the LF fiber comprises or consists essentially of highly polar liquids and/or charge transfer molecules having relatively high molecular dipole values. The liquid filled fiber is usable with a laser for differential frequency generation.
