摘要：

We constructed a CW fiber laser using a 40-mm-long Nd3+ heavily doped silica glass single-mode fiber (Nd-SMF). Its core glass was fabricated by the zeolite method, and its Nd2O3 doped density was measured as 1.25 wt%. Nd-SMF also demonstrated laser oscillation. The laser power reached 19.7 mW and its slope efficiency and laser threshold were 14.6% and 22.0 mW, respectively. Such a short single-mode fiber will help us easily make a high repetition rate over GHz and a compact oscillator with adequate saturable absorbers. An Nd-SMF laser has the potential to achieve laser miniaturization and high repetitive pulsed oscillation.
