%J 中国物理快报 %D 2010 %I %X We report stable narrow linewidth laser systems based on self-developed Littman configuration external cavity diode lasers (ECDLs). The frequency of the ECDL is stabilized to a high fineness ultralow-expansion glass reference cavity with the Pound-Drever-Hall technique. By heterodyne beating of two identical systems, we conclude that the linewidth of each ECDL is reduced to lower than 150 Hz and its frequency stability reaches 4.3× 10-14 at an averaging time of 1 s, the averaged long-term frequency drift is less than 0.2 Hz/s over 30 h measurement time. %K 42 %K 79 %K Gn %K 42 %K 55 %K Px %K 42 %K 60 %K Pk %K 37 %K 10 %K Jk %K 06 %K 20 %K fb
