“…The development of 589 nm lasers has been restrained by the lack of solid-state gain medium at this band. Dye lasers, optically pumped semiconductor lasers, and frequency sum mixing of 1064 and 1319 nm Nd:YAG lasers [4][5][6] have been developed to obtain 589 nm sources; however, these approaches suffer from high maintenance, low power, high complexity, or high cost. More recently, Raman fiber amplifiers (RFAs), with the advantages of high stability, compactness, wavelength agility, and high power, have shown promise for generating 589 nm sodium guide star lasers [7][8][9][10].…”

589 nm lasers pulsed at Larmor frequency, several hundreds of kilohertz, can increase the brightness of a sodium guide star and are required in remote magnetometry with mesospheric sodium. By amplification of a continuous-wave single-frequency 1178 nm laser in a pulse-pumped Raman fiber amplifier and frequency doubling in an external cavity, high-power pulsed 589 nm laser at Larmor frequency is obtained for the first time, to the best of our knowledge. The pulse format is mainly determined by the 1120 nm Raman pump laser, whose pulse repetition rate and duty cycle are adjustable. Active pulse shaping is applied to minimize the relaxation spike at the leading edge of the pulses. A reduction in pulse width and conversion efficiency from 1120 to 1178 nm is observed in the backwardly pumped Raman fiber amplifier due to the pump pulse transition effect. A 589 nm laser pulsed at a 350 kHz repetition rate and 20% duty cycle with average power up to 17 W is demonstrated as an operation example intended for a geomagnetic field of 0.5 G.

“…Since the first publications on dye lasers, research on mode selection in these lasers has focused mainly on methods for obtaining lasing with a narrow linewidth and a single longitudinal mode [14,15]. The number of works on transverse mode selection in dye lasers is extremely limited compared to the huge number of publications on this topic for solid-state lasers.…”

Investigations of structured laser beams formation are one of the attractive areas of laser research in recent years. Compared to solid-state lasers, dye lasers were rarely in demand in these studies. Here we present several transverse mode selection experiments in a pulsed Rhodamine 6G dye laser (λ = 580 nm) with a plano-spherical resonator under hollow beam pumping by 20 ns pulses of 532 nm radiation from the Nd:YAG laser 2-nd harmonic. Along with high-order vortex and petal Laguerre-Gaussian modes, a whole family of non-planar geometric modes of different structures was obtained at the frequency degenerate states of this dye laser resonator. The ensemble of geometric modes in the related degenerate resonator configurations is illustrated by fractal frequency spectrum calculations. The experiments performed show that a dye laser represents a fairly simple and convenient object for testing various mode selection techniques. Dye lasers operating in the visible and near-infrared spectral regions can complement the range of solid-state laser sources currently used for obtaining and studying structured laser beams, which have many applications in scientific research and applied problems.

“…Tunable single longitudinal mode (SLM) fiber lasers have recently become the focus of significant research efforts due to their potential for a wide range of applications such as high-resolution optical spectroscopy [1,2], communication systems [3][4][5] and microwave and photonic generation [6,7]. SLM fiber lasers are able to provide a highly stable, continuous wave output where the oscillation of multiple densely spaced longitudinal modes is prevented, thereby allowing only a single longitudinal mode to oscillate in the laser cavity.…”

A tunable, single-longitudinal-mode (SLM) fiber laser based on a short length, highly doped zirconia-erbium doped fiber (Zr-EDF) is proposed and demonstrated. The Zr-EDF is a novel fiber with an erbium ion concentration of 4320 ppm wt − 1 and an absorption rate of approximately 22.0 dB m − 1 at 978 nm, while at the same time being highly compatible with conventional silica-based optical fibers. The Zr-EDF is used as the gain medium in the laser cavity, while a tunable C-band fiber Bragg grating is used to adjust the operating wavelength of the system, providing an operating wavelength range of between 1533.8 nm to 1545.0 nm. Two short erbium-doped fibers, with active ion concentrations of 900 ppm wt − 1 , serve as saturable absorbers, and allow for an SLM output with a narrow laser linewidth of only 0.2 MHz. The proposed system has multiple applications as a tunable SLM laser for communications and sensing purposes.
