    Selection of operating wavelength of the Yb-doped fiber-ring lasers using long-period fiber gratings (LPFGs) is proposed. In the proposed method, customized LPFG that sustains high powers serves as a broad-band rejection filter. It modifies the net gain profile of the laser, enabling the peak gain to occur at a designed wavelength. The gratings were inscribed by CO2 laser and the grating period down to 175 μm was achieved being, to our best knowledge, the shortest reported LPFG period using this technique
