Abstract

Since Stolen and Tom demonstrated in 1987 that seeding germanosilicate fibers with the second harmonic results in rapid preparation⁽¹⁾, many fundamental questions about the physical mechanisms responsible remain unanswered. We have studied the temperature dependence, temporal correlation and intensity dependence of the preparation process for seeded fibers using an Nd: YAG laser and fibers with only Ge doping.
