AB - A single-mode Nd-doped solid-core anti-resonant fiber with core diameter of 27 m was designed for high-power 900 nm laser generation. The simulated result of the designed fiber shows that in the 870~900 nm band, the fundamental mode loss is less than 0.1 dB/m while all the higher-order mode losses are higher than 10 dB/m. More importantly, the loss of all the modes in the 1060 nm band is greater than 100 dB/m, which can guarantee high-power laser generation at 900 nm while suppressing the parasitic lasing around 1060 nm. Based on the designed Nd-doped fiber, a 900 nm fiber amplifier was simulated, which reveals that the amplified spontaneous emission around 1060 nm can be effectively suppressed and a laser slope efficiency up to 54% can be obtained from 0.5 m gain fiber with 100 mW of laser seed.
