“…Up to now, the major progress in the power scaling of SFFAs has been obtained at 1.0 μm, 1.5 μm, and 2.0 μm, and mostly endowed by the well-developed ytterbium-, erbium-and thulium-doped fiber (YDF, EDF, and TDF), as well as the corresponding pump sources and fiber components [5,13] . In addition, owing to the merits of a high pump absorption coefficient and low quantum defect (around 8%) of the YDF, it is more advantageous for scaling the output power of SFFAs than EDF and TDF.…”

“…Generally, single-frequency laser operation is realized from a laser cavity that has an oscillation mode spacing wide enough so that only a single oscillating mode can be retained with the aid of intra-cavity filtering components. The common practice is the employment of a short cavity length (several centimeters or even shorter), which incorporates a conventional narrowband filter that can realize stable SLM operation with a compact configuration [5] . At present, by using rare-earth ion-doped fibers, a solid-state crystal, or a semiconductor chip as the gain medium, single-frequency lasers with high performance output have been well-developed and even commercialized [6][7][8] .…”

Unlike conventional continuous-wave lasers with wide spectra, the amplification of single-frequency lasers in optical fibers is much more difficult owing to the ultra-high power spectral density induced nonlinear stimulated Brillouin scattering effect. Nevertheless, over the past two decades much effort has been devoted to improving the power scaling and performance of high-power single-frequency fiber amplifiers. These amplifiers are mostly driven by applications, such as high precision detection and metrology, and have benefited from the long coherence length, low noise, and excellent beam quality of this type of laser source. In this paper, we review the overall development of high-power single-frequency fiber amplifiers by focusing on its progress and challenges, specifically, the strategies for circumventing the stimulated Brillouin scattering and transverse mode instability effects that, at present, are the major limiting factors of the power scaling of the single-frequency fiber amplifiers. These factors are also thoroughly discussed in terms of free-space and all-fiber coupled architecture. In addition, we also examine the noise properties of single-frequency fiber amplifiers, along with corresponding noise reducing schemes. Finally, we briefly envision the future development of high-power single-frequency fiber amplifiers.

“…Compact cost-effective laser sources with tunable coherency are of the great demand for a number of potential applications [1][2][3][4][5][6][7][8][9] . Among them are high-resolution spectroscopy, phase-coherent optical communications, microwave photonics, coherent optical spectrum analyze, and distributed fiber optics sensing [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] .…”

We report on linewidth narrowing and stabilization of semiconductor DFB laser implemented through its self-injection locking to an external fiber ring cavity in conjunction with an active optoelectronic feedback circuit controlled by a simple low-cost USB-DAQ card. The system enables narrowing of the DFB laser linewidth below ~0.5 kHz and drastically reduced the laser phase noise. Specifically, the laser configuration is fully spliced from the polarization maintaining (PM) single-mode optical fiber that exhibits significantly improved stability against the environment noise. Drastic narrowing of the DFB laser linewidth down to ~310 Hz and a phase noise less than -100 dBc/Hz (>30 kHz) are achieved with the PM fiber ring cavity built from a single fiber coupler. The reported PM laser configuration is of great interest for many laser applications where a narrow sub-kHz linewidth, simple design and low cost are important.

“…A singlefrequency laser radiation (corresponding to generation at single longitudinal mode, SLM) is required for the absorption spectroscopy. SLM fiber lasers have a special place due to a combination of high reliability, radiation quality, and compactness [9]. Generation of SLM radiation is rather complicated task itself because of relatively large spectral bandwidth of the laser components (the amplification band of the active medium and/or reflection band of cavity mirrors, such as widely used fiber Bragg gratings (FBGs)) in comparison with the free spectral range (FSR) of the laser cavity.…”

The single-frequency holmium-doped fiber laser with spectral filtration based on a dynamics filter formed in heavily holmium-doped fiber is presented. The continuous wave lasing on a single longitudinal mode in the spectral region of 2.1 μm with an output power of 1.6 mW is shown when the filtering fiber is cooled with liquid nitrogen. The optical signal-to-noise ratio and the relative intensity noise were more than 30 dB and — 62.8 dB Hz−1, respectively. The developed source can be used for gas spectroscopy as well as for remote atmosphere sensing of such gases as carbon dioxide, nitric oxide, ammonia, carbon monoxide and others.
