Efficient single-longitudinal-mode Nd:YAG laser

IEEE Journal of Quantum Electronics, 1972
A continuous TEM 00 power of more than \frac{1}{2} W has been obtained from a single-longitudinal-mode (SLM) Nd:YAG laser pumped with a 1-kW tungsten-iodine lamp. Spatial hole burning, the cause of multilongitudinal mode (MLM) oscillation, was eliminated by placing the rod between two quarter-wave plates.

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.

Mode evolution mechanism of Pr3+:YLF single longitudinal mode laser

Applied Physics B, 2020
We develop a theoretical model of multimode rate equation that accurately describes mode evolution mechanism of prelase Q-switched Pr3+:YLF single longitudinal mode (SLM). We find that it is important to consider the effect of gain difference when calculating the mode competition time accurately.

High-efficiency single-longitudinal-mode laser

OSA Annual Meeting, 1993
This is a new type laser composed by two resonators. It conquers the contradiction between the efficiency and the quality of single longitudinal mode (SLM), and there is no strict matching requirement for resonator and modes of injection locking.

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 ...

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.

Grating-tuned, single-longitudinal-mode, diode-pumped Nd:YVO_4 laser

Optics Letters, 1993
Single-longitudinal-mode output as great as 1 mJ has been obtained from a grating-tuned Nd:YVO4 laser pumped by a quasi-cw laser-diode array. A simple cavity design containing a diffraction grating at a high angle of incidence has permitted the output to be tuned over a wavelength range of greater than 1 nm.

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.
