The influence of mode partition fluctuations in nearly single longitudinal mode lasers
Journal of Lightwave Technology, 1986A simple relationship between the mode ratio of a two-mode laser and an empirical mode partition coefficient is derived. The effects of the mode ratio of a two-mode laser on the bit-error-rate floor of an optical fiber system are calculated, and the power penalties due to mode partitioning in the presence of Gaussian receiver noise are evaluated.

Comparison Between Single-Longitudinal-Mode and Two-Longitudinal-Mode Pumping Cavity OPSMMWL
International Journal of Infrared and Millimeter Waves, 2002A 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 ...

RTP Q-switched single-longitudinal-mode Nd:YAG laser with a twisted-mode cavity
Applied Optics, 2015This paper describes a high pulse repetition frequency Nd:YAG twisted-mode laser that uses an RTP crystal as the electro-optic Q-switch. Stable single-longitudinal-mode laser beams at 1, 5, and 10 kHz were obtained with a linewidth less than 0.1 GHz.

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.

Resonantly pumped single-longitudinal-mode Ho:YAG laser
Applied Physics B, 2016We demonstrated a 1.9-μm-pumped high-efficiency single-longitudinal-mode Ho:YAG laser with intra-cavity etalons for the first time. By inserting the F–P etalons into the laser cavity, single-longitudinal-mode Ho:YAG lasing was achieved at a wavelength of 2081.2 nm.

III Single-Longitudinal-Mode Semiconductor Lasers
1988Publisher Summary This chapter discusses the single-longitudinal-mode (SLM) semiconductor lasers. The use of single-mode fibers has eliminated the problem of modal noise. The chapter reviews the recent progress in the field of SLM semiconductor lasers. The physics of semiconductor lasers is discussed and the material system and the structure commonly

Single-longitudinal-mode laser as a discrete dynamical system
Journal of the Optical Society of America B, 1985A solid-state laser running on a single longitudinal mode can show chaotic time behavior if several transverse modes are excited. The temporal development of the laser is approximated by a Kirchhoff integral together with a rate equation for the inversion.

Partition fluctuations in nearly single-longitudinal-mode lasers
Journal of Lightwave Technology, 1984A simple model of mode partition noise is developed, which is valid for semiconductor lasers operating CW, having a single active region and oscillating primarily in one dominant mode. It is shown that the intensity fluctuations in the nonlasing modes occur with characteristic times of a few nanoseconds and have exponential probability distributions ...
