Gas-filled hollow-core photonic crystal fibers are used to stabilize a fiber laser to the 13C2H2 P(16) (ν1+ν3) transition at 1542 nm using saturated absorption. Four hollow-core fibers with different crystal structure are compared in terms of long term lock-point repeatability and fractional frequency instability. The locked fiber laser shows a fractional frequency instability below 4 × 10(-12) for averaging time up to 10(4) s. The lock-point repeatability over more than 1 year is 1.3 × 10(-11), corresponding to a standard deviation of 2.5 kHz. A complete experimental investigation of the light-matter interaction between the spatial modes excited in the fibers and the frequency of the locked laser is presented. A simple theoretical model that explains the interaction is also developed.
充气空心光子晶体光纤用于通过饱和吸收将光纤激光器稳定到1542 nm处的13C2H2 P(16) (ν1+ν3)跃迁。比较了四种具有不同晶体结构的空心光纤在长期锁定点重复性和分数频率不稳定性方面的情况。对于平均时间长达10^4秒，锁定的光纤激光器显示出低于4×10^(-12)的分数频率不稳定性。超过1年的锁定点重复性为1.3×10^(-11)，对应于2.5 kHz的标准差。给出了对光纤中激发的空间模式与锁定激光器频率之间光与物质相互作用的完整实验研究。还开发了一个解释这种相互作用的简单理论模型。
