A high-efficiency fiber laser at 1018 nm using homemade Yb-doped phosphosilicate fiber is demonstrated. The fiber shows blueshifted emission spectrum compared to Yb-doped aluminosilicate fiber, and is considered favorable for the short wavelength Yb-doped fiber laser. With a 7 m gain fiber, up to 22.8 W output at 1018 nm is achieved with an optical efficiency of 53%. The amplified spontaneous emission at 1030 nm is suppressed to 50 dB below the 1018 nm laser. This work shows that highly-efficient fiber laser at 1018 nm can be obtained with Yb-doped phosphosilicate fiber.
展示了一种使用自制掺镱磷硅酸盐光纤的1018nm高效光纤激光器。与掺镱铝硅酸盐光纤相比，该光纤的发射光谱发生蓝移，被认为有利于短波长掺镱光纤激光器。使用7m增益光纤，在1018nm处实现了高达22.8W的输出，光效率为53%。1030nm处的放大自发辐射被抑制到比1018nm激光低50dB。这项工作表明，使用掺镱磷硅酸盐光纤可以获得1018nm的高效光纤激光器。
