“…It may be observed that our proposed amplifier design with optimized parameters has better performance as compared to the results of the past studies as mentioned in [5,[12][13][14]16]. There are few past studies in the literature [22,26,27] in which the authors have demonstrated higher peak gains and output powers as compared to the same in the proposed work. The design of the HDFA proposed in [26,27] is based on multi-stage pumping and the design of [22] exploits shared pump double-stage pumping while our optimized design is based on a single forward pump source and a single short piece of HDF.…”

In this paper, we address the performance optimization of Holmium doped fiber amplifier (HDFA) for optical communications in 2–2.15 μm wavelength range based on a single in-band forward pump source. The performance of the HDFA is analyzed with the help of theoretical simulations by considering an optimized length of Holmium doped fiber (HDF), doping concentration of Ho3+, and pump power. The impact of signal wavelength and power on gain, amplified spontaneous emission (ASE) noise, and noise figure (NF) of the amplifier is investigated. Furthermore, we investigate the variations in the gain of the amplifier, its output power, and NF by varying the power and wavelength of the pump source. After optimizing the parameters of the amplifier, the peak gain observed is around 56.5 dB, the 3 dB saturated output power obtained is 33.3 dBm, and the output power is 3 W at signal wavelength of 2.0321 μm for HDF having an optimized length of 12 m and pump power of 3.5 W. Minimum NF of around 8.2 dB is observed at 2.0321 μm for signal power of −5 dBm. The impact of ion-ion interaction on the performance of HDFA is also investigated. A reduction of 24.2 dB and 0.051 W is observed in peak gain and output power of HDFA, respectively by considering the ion-ion interaction.

“…We note that Tm-doped fiber lasers can readily be engineered to produce multiwatt output powers over a wavelength band spanning 1800-1980 nm and more. To verify our hypotheses in a systematic way, we studied through simulations [10][11][12] the performance of a 3 m long Ho-doped amplifier in Fig. 2 as a function of pump wavelength.…”

“…3 m length was chosen based on previous optimization studies. Our simulations were carried out using proprietary software [10][11][12] using the Giles method [21,22] and fourth order Runge-Kutta algorithms, and incorporated a core diameter of 8 microns, an NA of 0.16, background losses of 200 dB/m for both pump and the signal wavelengths, and an ion pairing coefficient of 13.5%. This ion pairing coefficient is consistent with the experimental results in [23] and is typical of existing Ho-doped fibers in manufacture.…”

We report the design and performance of medium slope efficiency (64%) Holmium-doped fiber amplifiers (HDFAs) with novel alternative in-band pump wavelengths in the 1720-2000 nm spectral region. We demonstrate through simulations that pump wavelengths of 1840-1860 nm can yield significantly improved output power, gain, and optical-optical conversion efficiency compared to the previous technical and industry standard pump wavelength of 1940 nm. Our simulations are verified by experimental data.

“…However, such resonator's linewidth is typically too high, and the radiation is not polarized. In monolithic, polarization maintaining amplifier configurations, the average power typically is in the region < 10 W [5,6]. While the resonator configurations show the potential for power scaling, monolithic, polarization maintaining amplifier configurations must still be further developed.…”

Within the context of the E-TEST (Einstein Telescope EMR Site & Technology) project, Fraunhofer ILT develops thulium-and holmium-based seed sources and fiber lasers at app. 2 µm wavelength with highest demands on linewidth and stability for usage in a third-generation gravitational wave detector, the Einstein telescope. To fulfill the requirements, we develop a seed laser and a multi-stage fiber amplifier, consisting of holmium-doped fibers. Within this paper, we present our current laser concept and the first results of our dual-stage holmium-doped fiber amplifier stage. We achieve a low linewidth (< 2 MHz) output power of more than 5 W at a wavelength of 2095 nm. By using our in-house developed fiber laser simulation, we show that the efficiency of our amplifier is currently limited by pair induced quenching and the potential for further power scaling.
