Tunable single-longitudinal-mode fiber optical parametric oscillator

Optics Letters, 2010
A tunable single-longitudinal-mode (SLM) fiber optical parametric oscillator (FOPO) is proposed and demonstrated experimentally. A sub-ring cavity with a short cavity length is used to suppress the longitudinal modes and broaden the longitudinal mode spacing.

A tunable and single-longitudinal-mode Ho:YLF laser

Infrared Physics and Technology, 2016
Abstract A 1.94 μm Tm-doped fiber laser pumped tunable single-longitudinal-mode Ho:YLF laser with double etalons was reported for the first time. The maximum single-longitudinal-mode output power of 345 mW at 2051.6 nm was achieved at the absorbed pump power of 11.9 W, corresponding to a slope efficiency of 5.5% and an optical conversion efficiency ...

Single longitudinal mode operation of a fibre laser [PDF]

, 1987
We report the first operation of a monomode fibre laser oscillating on a single longitudinal mode. The laser incorporates an integral fibre grating and the output linewidth is 1.3MHz FWHM.

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.

Comparison Between Single-Longitudinal-Mode and Two-Longitudinal-Mode Pumping Cavity OPSMMWL

International Journal of Infrared and Millimeter Waves, 2002
A CO2 infrared laser system with a etalon to be the longitudinal mode select equipment was set up to be the optically pump source, as well as a mini NH3 with 20cm long sample tube to be the sub-millimeter wave laser. CO2-9R(16) line was chose to pump the mini-NH3 SMMW laser, and 90.4um SMMW line was obtained by single-longtudinal-mode or two ...

Single-longitudinal-mode ring diamond Raman laser

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
We demonstrate a single-longitudinal-mode ring diamond Raman laser, pumped by a tunable single-mode Ti:sapphire laser. Two methods to achieving unidirectional operation have been demonstrated: increasing gain for one direction using a reinjecting mirror and increasing loss for one direction using sum frequency mixing in BBO.

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.

Single longitudinal mode operation of diode lasers

Applied Physics Letters, 1977
We report single longitudinal mode operation of conventional double-heterostructure GaAs/GaAlAs diode lasers achieved by heavy p-type doping of the active region. At 77 °K a broad-area device pumped with a rectangular current pulse exhibited single longitudinal mode operation up to 2.8 times threshold, which was the limit of the pulser.
