Journal ArticleDOI
Threshold, time, and spectral characteristics of a fiber laser
TL;DR: In this paper, the time and spectral properties of a glass-fiber laser with a core doped with 6 wt.% Nd2O3 were analyzed at the stimulated emission threshold and below and above it.
Journal ArticleDOI

Journal ArticleDOI
Substructure of high-power stimulated emission pulses from a fiber laser
TL;DR: In this article, it was demonstrated experimentally that an individual spike in a regular series of intensity pulsations from a glass-fiber laser having a core doped with neodymium ions, consists of a train of short pulses having a duration of 2-8 nsec and a period of ~15 nsec.

TL;DR: In this paper, it was found experimentally that stimulated emission from a fiber laser made of neodymium-doped phosphate glass could operate in quasi-cw and structured spike regimes, depending on the content of cerium oxide in the glass.
