Abstract

Power scaling of nanosecond fiber laser pulses with narrow linewidth has been demonstrated by using a new single-mode (SM) large-core polarization maintaining (PM) highly Er/Yb co-doped phosphate glass fiber (EYPhF). We used an optimized length of 12 cm of the EYPhF fiber in the power amplifier of the all-fiber MOPA chain. The pulse energy can reach 0.11 mJ for the amplified pulsed fiber laser, which corresponds to a peak power of 51.5 KW with pulse duration of 2.1 ns and repetition rate of 5 KHz. This high power pulsed fiber laser has an estimated linewidth of < 500 MHz.
