Single-longitudinal-mode multiwavelength fiber ring laser

IEEE Photonics Technology Letters, 2004
A single-longitudinal-mode multiwavelength fiber ring laser is proposed and demonstrated. The single-longitudinal-mode operation is realized using a fiber loop mirror with a saturable absorber. The fiber loop mirror acts as a passive self-tracking narrow multiband optical filter.

Transverse-mode selection in single-longitudinal-mode lasers

Physical Review A, 1996
In this paper we analyze the transverse pattern-forming characteristics of a two-level and single-longitudinalmode laser. The corrections to the classical empty cavity modes due to pumping and losses are specifically considered, leading to different excitation rates for the different transverse modes.

Single-longitudinal-mode broadband tunable random laser

Optics Letters, 2017
In this work, we demonstrate a broadband tunable single-longitudinal-mode (SLM) random laser based on Rayleigh backscattering in a standard single-mode fiber. The wide tuning range of this SLM fiber laser over 1500-1570 nm is demonstrated with a linewidth of 4.5-30 kHz.
