Single-longitudinal-mode, tunable, pulsed Ti:sapphire laser oscillator

Optics Letters, 1989
A 2.0-mJ/pulse, 2-nsec, single-longitudinal-mode Ti:sapphire laser oscillator has been demonstrated in a compact grazing-incidence cavity configuration similar to a Littman arrangement. The oscillator's output beam quality is TEM(00), making it attractive for doubling and mixing applications.

Single longitudinal mode oscillation from a multi-interferometric cavity

Applied Optics, 2009
A method to generate stable single longitudinal mode (SLM) radiation from a multi-interferometric cavity configuration that can be considered as the combination of one Michelson cavity and two Fox-Smith cavities is presented. A numerical model of the interferometric cavity is investigated to optimize the laser for mode selection, and experimental ...

Mode stability analysis of nearly single-longitudinal-mode semiconductor lasers

IEEE Journal of Quantum Electronics, 1988
Power fluctuations in the main mode of a nearly single-longitudinal-mode AlGaAs laser are investigated. Average CW mode powers were measured to analyze the static characteristics of oscillation. For the dynamic characteristics, the escape probability was measured to evaluate the magnitude and the frequency of fluctuations.

Single Longitudinal Mode Modified CSP Injection Laser for Single-Mode Optical Fiber

1982
Stable single transverse and longitudinal mode cw operation has been demonstrated using a newly developed gaussian channel substrate (GCSP) laser structure. These devices operate in excess of 14mW and are predominately single longitudinal mode over their entire operating range.

The influence of mode partition fluctuations in nearly single longitudinal mode lasers

Journal of Lightwave Technology, 1986
A 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.

Single-longitudinal-mode(SLM) fiber ring laser based on semicircular single mode fiberstructure

2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017
A single longitudinal mode (SLM) fiber ring laser based on a semicircular single mode fiber (SSMF) structure is proposed. In the fiber ring laser, a piece of erbium doped fiber (EDF) pumped by a 980 nm semiconductor laser diode (LD) through a wavelength division multiplexer (WDM).A fiber Bragg grating (FBG) is used as a filter.

RTP Q-switched single-longitudinal-mode Nd:YAG laser with a twisted-mode cavity

Applied Optics, 2015
This 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.

Low-order longitudinal modes of single-component plasmas

Physics of Plasmas, 1995
The low-order modes of spheroidal, pure electron plasmas have been studied experimentally, both in a cylindrical electrode structure and in a quadrupole trap. Comparison is made between measurements of mode frequencies, recent analytical theories, and numerical simulations.

Single Transverse and Longitudinal Mode Operation of Semiconductor Lasers

Integrated and Guided Wave Optics, 1978
Single transverse and longitudinal mode operation of semiconductor lasers is an ultimate objective of laser device designing. It has recently been demonstrated that the transverse mode instability encountered in conventional stripe-geometry (AlGa)As lasers can be prevented by introducing a passive waveguide structure: a channeled-substrate-planar (CSP)
