In this Letter, a 1-μm-wavelength fiber laser is proposed through the use of the ytterbium-doped active fiber and the third harmonic Bragg reflectors. Benefiting from the ratio below 0.5 between the core diameter of the fiber and the Talbot length of the UV fringes, enabling the formation of the secondary-type-In grating, the reflector with reflectivity… CONTINUE READING
