Efficient single-longitudinal-mode Nd:YAG laser
IEEE Journal of Quantum Electronics, 1972A 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 oscillation from a multi-interferometric cavity
Applied Optics, 2009A 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 ...

High-efficiency single-longitudinal-mode laser
OSA Annual Meeting, 1993This 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.

Grating-tuned, single-longitudinal-mode, diode-pumped Nd:YVO_4 laser
Optics Letters, 1993Single-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, 1988Power 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.

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 ...

Tm-fiber pumped single-longitudinal-mode Ho:LuVO4 laser
Optical and Quantum Electronics, 2016We demonstrated a Tm-fiber pumped single-longitudinal-mode Ho:LuVO4 laser with intra-cavity Fabry–Perot etalons. By the use of an output coupler with a transmission of 2%, the Ho:LuVO4 laser generated a continuous-wave output power of 609 mW at 2074.72 nm.
