摘要：

We demonstrate the frequency stabilization of a high output power, erbium silica fiber laser by utilizing a (C2H2)-C-13 (acetylene) absorption line at 1538.8 nm and a (HCN)-C-13-N-14 (hydrogen cyanide) absorption line at 1549.73 nm. We introduced a novel short ring cavity configuration and pump power feedback control to suppress the intensity noise of the laser output, which is caused by the relaxation oscillation of erbium ions. As a result, we succeeded in simultaneously obtaining a stable single-frequency oscillation with an output power of over 290 mW, a linewidth of 5 kHz, and a low relative intensity noise (RIN) of -120 dBHz. The frequency stabilities reached 2.8 x 10(-11) and 6.9 x 10(-11) for an integration time of 1 s with a (C2H2)-C-13 and a (HCN)-C-13-N-14 absorption line, respectively.
