我们进行了详细的研究，短，掺铒光纤激光器的稳定性与两个紫外光诱导布拉格光栅写入到掺杂光纤。我们发现，单纵模光纤光栅激光器的相对强度噪声是约3个数量级低于单频1.523-妈妈氦氖激光器。频率噪声频谱包含很少的谐振，没有一个谐振超过0.6 kHz/Hz（1/2）rms;从50 Hz到63 kHz的积分均方根频率噪声为36 kHz。我们还展示了一个简单的方法来监测激光功率和振荡模式的数量在激光制造。
We conducted a detailed study of the stability of short, erbium-doped fiber lasers fabricated with two UV-induced Bragg gratings written into the doped fiber. We find that the relative intensity noise of single-longitudinal-mode fiber grating lasers is approximately 3 orders of magnitude lower than that of a single-frequency 1.523-mum helium-neon laser. The frequency noise spectrum contains few resonances, none of which exceeds 0.6 kHz/Hz(1/2) rms; the integrated rms frequency noise from 50 Hz to 63 kHz is 36 kHz. We also demonstrate a simple method for monitoring the laser power and number of oscillating modes during laser fabrication.
