Over the past decade, significant advancements have been made in studying and developing fiber lasers and amplifiers, operating from continuous-wave (CW) to femtosecond pulse durations. This progress is mainly due to the advantages of diode-pumped fiber laser sources over traditional solid-state lasers, including high beam quality, near-quantum-limited efficiency, simplified thermal management, and compactness. In this talk, we begin by reviewing our recent research on Tm³⁺- and Er³⁺-doped mode-locked fiber lasers, where nanoengineered gain fibers and innovative cavity designs enable high-efficiency lasers and novel soliton operation. We then discuss the development of a high-power Yb³⁺-doped fiber laser amplifier designed to generate 13.5-nm EUV through laser-produced plasma technology. In addition, we present our work on novel side-coupling technologies, including subwavelength gratings reflectors and fiber combiners. Finally, we explore the potential of these fiber laser sources for advanced scientific applications.
