Abstract :
A 1060 nm band Ytterbium doped fiber (YDF) laser is proposed and investigated. Using 70 cm YDF and FBG parameter optimization reflectivity and pumping scheme, a high slope efficiency of 50% and low threshold power are obtained. The power variation is less than 0.1 dB in 13 nm tuning span. Using multiple subring cavities as the mode filter, known as Vernier effect, near single frequency lasing is realized for a 13 nm tuning range in 1060 nm band with 2 dBm output power.
