✦ Synopsis

Single-frequency output power of 12 W at 1064 nm is demonstrated. Pumped by a fiber-coupled diode laser, the Nd:YVO 4 produces 58.6% of the slope efficiency with respect to absorbed pump power, and 52.7% of the optical-optical efficiency and nearly diffraction-limited output with a beam quality parameter of M 2 ≈ 1.11. To the best of our knowledge, this is the highest slope efficiency and optical-optical efficiency in singlefrequency Nd:YVO 4 ring laser. The slope efficiency of the single frequency laser is close to the limit of the efficiency.

## Abstract To realize single‐frequency of the fiber laser, a ring configuration is devised. The single‐frequency operation is realized at 1549.63 nm by using a fiber Bragg grating (FBG) as wavelength‐selective element and a unpumped 1.5 m‐long erbium‐doped fiber, which can produce standing‐wave sa
