Abstract

Recently, an interesting pulsing behavior of a fiber laser with intracavity Raman conversion was reported [ Y. Zhao and S. D. Jackson, Opt. Lett. 31, 751 (2006) ]. The pulsing has been interpreted as passive Q switching, but this interpretation needs to be revised. An alternative explanation predicts transient phenomena, which do not lead to a regular pulse train.

Peak power of the fundamental pulse (upper diagram) and the Raman pulse (lower diagram) versus position in the laser (with logarithmic vertical scales). Light traveling at different positions (indicated as 1, 2) relative to the main pulse (filled circle) experiences different levels of loss via Raman conversion and thus different round-trip gain.
