Summary: The article describes the design and characterization of a tunable narrow linewidth thulium-doped fiber laser source that combines core-pumped preamplifiers and high-power cladding-pumped amplifiers, providing >80 W average power. The digitally tunable single-frequency wavelength output from 1.92 μm to 2.01 μm can target specific atmospheric absorption and transmission windows for applications aiming at atmospheric transmission at 2 μm. Results from preliminary thermal blooming studies are presented.

Summary: A high-power continuous-wave single-frequency 1530 nm Er:Yb co-doped fiber amplifier using polarization-maintaining fiber as the gain medium is demonstrated. Core pumping with a 1480 nm Raman fiber laser is utilized to achieve the required population inversion for efficient 1530 nm amplification. Numerical simulation proves the advantage of 1480 nm core-pumping over the usual 9xx nm diode cladding pumping. The obtained maximum single-frequency 1530 nm laser power is 45.5 W with an amplified spontaneous emission suppression ratio of 46 dB, corresponding to an optical efficiency of 74%.

Summary: In this paper, the overall development of high-power single-frequency fiber amplifiers is reviewed, with a focus on progress, challenges, and future prospects. Strategies for circumventing stimulated Brillouin scattering and transverse mode instability effects, which are the major limiting factors of power scaling, are discussed in detail. The noise properties and corresponding noise reducing schemes of single-frequency fiber amplifiers are also examined.

Summary: This paper presents the design and performance of a packaged broadband PM hybrid HDFA/TDFA in the 2000-2100 nm band using all-single-clad doped fibers. Good results in terms of internal signal gain, noise figure, and output power are achieved at 2051 nm. Comparison between experimental data and simulations shows good agreement. Simulations of an all-Holmium two-stage PM optical amplifier design were also conducted for comparison with the hybrid PM HDFA/TDFA.

Summary: In this study, a stable single-longitudinal-mode thulium-doped fiber laser (TDFL) was combined with a phase-shift fiber Bragg grating, uniform fiber Bragg grating, and a double-coupler-based double-ring filter for mode selection. The experimental results demonstrated exceptional performance of the proposed filter, with minimal fluctuations in center wavelength and optical power. The proposed TDFL also exhibited a narrow linewidth and low relative intensity noise, making it ideal for free-space optical communication applications.

Summary: This study presents a multi-wavelength thulium-doped fiber laser using two cascaded single-mode-four-mode-single-mode fiber interferometers and a highly nonlinear fiber. By adjusting different lengths of four-mode fibers, specific wavelengths can be selected and more laser lines can be stimulated, resulting in 31 lasing lines covering a wavelength range of around 22 nm. The power fluctuation and wavelength drift for the 31-wavelength operation of the fiber laser are within 0.706 dB and 0.02 nm, respectively.

Summary: In this work, an all-fiber supercontinuum (SC) source with a record average output power of 714 W and a spectrum ranging from 690 nm to 2350 nm is demonstrated. The high-power SC output is achieved through the method of SC generation from an ytterbium-doped fiber amplifier. The source also exhibits a flat spectrum ranging from 1050 nm to 2095 nm. The potential to further increase the SC output power to the kilowatt level is highlighted.

Summary: Design studies for next-generation interferometric gravitational wave detectors propose the use of low-noise single-frequency high-power laser sources at 1064 nm. Fiber amplifiers are a promising design option, and coherent beam combining with independently amplified beams from two low-noise high-power single-frequency fiber amplifiers has successfully achieved a combined beam with high optical power.

Summary: This paper investigates the performance of a confined-doped active fiber fabricated in-house for all-fiber high-power single-frequency amplifiers. A 210-W single-frequency single-mode fiber laser is obtained, confirming the excellent performance of the confined-doped active fiber. The power scalability of the fiber amplifier is further demonstrated through the application of a temperature gradient along the active fiber, resulting in up to 75% enhancement of the stimulated Brillouin scattering (SBS) threshold. A 368-W single-frequency fiber laser with a beam quality factor of Mx2.1.19, My2.1.26 is achieved. Overall, the confined-doped active fiber technique shows promise for scaling the output power of single-frequency single-mode fiber lasers.

Summary: This paper proposes a strategy to achieve all-fiber single-frequency amplifiers with near-diffraction-limited beam quality using confined-doped fiber. By utilizing the large mode area and mode selection properties of the confine-doped fiber, the effects of stimulated Brillouin scattering and transverse mode instability are effectively suppressed. Experimental results show that the proposed amplifier can achieve high-power, single-frequency laser with improved beam quality compared to traditional designs.

Summary: This study proposes a high-spatial-resolution optical frequency domain reflectometry method with a single interferometer, using a self-compensation technique to successfully eliminate phase noise and obtain a compensated signal with high signal-to-noise ratio. The high spatial resolution is achieved by analyzing the length of the delay fiber at different measurement distances. This method has great potential in the field of distributed measurement.
