Abstract
Frequency-doubling fibers were annealed at various temperatures. The c onversion efficiency was monitored and found to drop by orders of magn itude at temperatures of approximately 200-400-degrees-C. An activatio n energy of 0.28 +/- 0.04 eV was inferred from these measurements for a Ge-doped fiber and of 0.40 +/- 0.08 eV for a Ge- and P-doped fiber. The decay of the second-harmonic conversion efficiency in time was als o studied.
