abstract = "High-power single-frequency laser oscillators, ranging from tens to even hundreds of watts, are in high demand for specialized applications such as quantum information processing and laser interferometer gravitational-wave observatories. In this paper, we present numerical investigations into the power scalability of single-frequency distributed Bragg reflector (DBR) ytterbium (Yb3+)-doped phosphate fiber lasers. We propose a low quantum defect (QD) operational approach to achieve 10-watt single-frequency laser oscillators, optimized using a figure of merit defined as the ratio of laser efficiency to quantum defect. Additionally, we report preliminary experimental investigations into the power scaling of low-QD Yb3+-doped phosphate fiber lasers.",
