摘　　要：将保偏全光纤环形谐振腔作为转移腔,实现了1550 nm参考激光器到1572 nm从激光器的频率稳定度转移,并研究了温度对光纤谐振腔长期稳定性的影响。理论和实验表明,仅通过压电陶瓷调谐腔长不能很好地实现频率稳定度转移。因此,提出用压电陶瓷快反馈和温控实现环形腔的稳定度转移,可使从激光器的频率稳定度在积分时间为1 s时的阿伦方差为2×10^-12,在积分时间为1000 s时的阿伦方差为5×10^-12。Using polarization-maintaining all-fiber ring resonator as the transfer cavity,a frequency stability transfer from 1550 nm reference laser to 1572 nm slave laser is realized in this work.The influence of temperature on the long-term stability of the fiber resonator is studied.Theoretical and experimental results show that the frequency stability transfer could not be realized well only by tuning the cavity length of piezoelectric ceramic resonator.Therefore,it is proposed to realize the stability transfer of the ring resonator by using piezoelectric ceramic fast feedback and temperature control.The Allan variance of the frequency stability of the slave laser is 2×10^-12 when the integration time is 1 s and 5×10^-12 when the integration time is 1000 s.
