We report on a narrowband 5 W cw fiber laser incorporating a point-by-point fiber Bragg grating inscribed into the core of a Yb 3+ -doped double-clad fiber. The laser featured excellent long-term wavelength and power stability (0.3%), as well as a very narrow ͑15 pm͒ linewidth, when passive temperature stabilization of the grating was implemented.
