Efficient amplification using the ⁴F_3/2→⁴I_9/2 transition in Nd-doped silica fiber

Research output: Contribution to journal › Article › peer-review

Abstract

Amplification characteristics of the three-level ⁴F_3/2→⁴I_9/2 transition in Nd-doped silica glass fiber are investigated under strong signal saturation and high pump power (150 mW). Aluminum codoped Nd-silica fibers exhibit strong superfluorescent behavior in the four-level ⁴_3/2→⁴I_11/2 transition which limits the optical conversion efficiency into the three-level transition. Ge-doped silica fibers do not exhibit this limitation and can efficiently amplify in the three-level transition with current laser-diode pump technology.
