“…It should be noted that observed pulsed intensity dynamics is typical for passive Q-switch lasers with SA. Similar pulsed behavior was also observed in DFB HDF fiber laser [22,29,30] and FP HDFLs.…”

“…Singlefrequency generation is obtained at 2.914 µm in a similar DBR scheme [21]. An HDF DFB laser with a length of only 42 mm generating SLM radiation with output power of 50 mW and a linewidth of about 10 kHz near wavelength of 2.07 µm is presented in [22]. It should be noted that all above-mentioned HDF lasers are based on DBR or DFB configurations, for which special techniques for constructing short cavities (for example, DFB cavity recording with fs-modification [22,28]) are required.…”

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.

“…In 24 the authors propose a new technique for introducing phase shifts into the FBG structure during the writing of point-by-point FBGs with femtosecond laser pulses at 1,026 nm. In 25 this technique was successfully applied for the realization of all-fiber DFB laser at 2.07 μm based on optical fiber with aluminosilicate glass core heavily doped with holmium ions.…”

Specially designed composite heavily er 3+-doped fiber in combination with unique point-by-point inscription technology by femtosecond pulses at 1,026 nm enables formation of distributed-feedback (DFB) laser with ultra-short cavity length of 5.3 mm whose parameters are comparable and even better than those for conventional er 3+-doped fiber DFB lasers having much longer cavity. The composite fiber was fabricated by melting rare-earth doped phosphate glass in silica tube. The ultrashort DFB laser generates single-polarization single-frequency radiation at 1,550 nm with narrow linewidth (3.5 kHz) and 0.5 mW output power at 600 mW 980-nm pumping. The same fiber with conventional CW UV (244 nm) inscription technology using phase mask enables fabrication of 40-mm long DFB laser with > 18 mW output power at 3.3% pump conversion, which is a record efficiency for er 3+-doped fiber DFB lasers. The developed technologies form an advanced platform for Er 3+-doped fiber DFB lasers operating around 1.55 µm with excellent output characteristics and unique practical features, in particular, the ultra-short DfB lasers are attractive for sensing applications.

“…In the longer wavelength, Ho 3+ -doped fiber is always used as the gain medium owing to its longer emission edge. In 2019, researchers in Novosibirsk State University have demonstrated a 2070 nm single-frequency Ho 3+ -doped fiber laser based on DFB scheme [59]. At room temperature, the laser yielded a maximum output power of 12.5 mW at 5.2 W pump power.…”

High-power single-frequency fiber lasers have attracted great attention in the applications of high-resolution spectroscopy, long-distance coherent communication, gravitational wave detection and some other areas, due to the advantage on narrow linewidth, low noise and so on. In this paper, we systematically summarize the recent achievements of high-power singlefrequency fiber laser oscillators and amplifiers as well as performance improvement on noise suppression, linewidth narrowing, and wavelength extension. Besides, the next development of SFFLs has been prospected.
