|摘要:||A 1,064 nm band Ytterbium doped fiber laser (YDFL) is proposed and investigated. Using 70 cm gain fiber and recycling pumping scheme, a high slope efficiency of 50 % and low threshold power of 53 mW are obtained. The power variation is less than 0.1 dB in 13 nm tuning span. Using the Vernier effect, near single frequency lasing is realized for the whole tuning range in 2 dBm output power. Have advantages of simpler structure, larger pump slope efficiency and possible shorter cavity, the YDFL may find potential applications in various ways.|
