摘　　要：基于低温稀土离子掺杂晶体中的光谱烧孔效应的激光稳频技术,以低温下稀土离子掺杂晶体中的光谱烧孔为频率锁定参考,有更低的热噪声极限,而且,与基于法布里-珀罗参考腔的激光稳频技术相比,该技术具有对外界温度、压力和加速度的变化更不敏感的优势,因此其频率稳定度理论上可达10^-17量级,能实现与法布里-珀罗参考腔可比拟甚至超越的稳频效果。从理论原理、技术实现、国内外研究进展几方面介绍了基于光谱烧孔效应的激光稳频技术,并对其在频率稳定技术领域的发展前景进行了展望。Laser frequency stabilization based on the spectral hole-burning effect in the cryogenic rare-earth-iondoped crystal makes use of the spectral holes in the absorption of doped ions as the frequency reference.This technique has a low thermal noise limit.In comparison with the laser frequency stabilization technique based on the Fabry-Perot cavity,the proposed laser frequency stabilization technique is more insensitive to temperature,pressure,and acceleration,thereby featuring its viability to let frequency stabilization reach the theoretical limit of 10^-17,which is comparable or even beyond with that of a Fabry-Perot cavity.The laser frequency stabilization technique based on spectral hole-burning effect is introduced from the aspects of theoretical principle,technical realization,and research progress at home and abroad.Furthermore,its development trend in the field of frequency stabilization is prospected.
