title = "Power scaling of Narrow-Linewidth Holmium-doped Fiber Amplifiers with low Noise and linear Polarization",
abstract = "We present our continuous-wave holmium-doped fiber amplifier operating at a wavelength of 2095 nm which delivers >10 W output power with linear polarization, narrow linewidth, and excellent beam quality. Our relative intensity noise (RIN) analysis shows a high power-stability over a broad frequency range, demonstrating the suitability of our approach to achieve high power stabilities. To investigate the power scaling capability of our holmium-doped fiber amplifier, and to further increase its output power and optical-optical efficiency, we tested several fibers achieving slope efficiencies of up to 57\%. By performing detailed design studies, we calculated that slope efficiency up to approx. 80\% are achievable by optimizing the fiber amplifier architecture and reducing the number of clustered ions in the holmium-doped fiber.",
