摘要/Abstract

摘要： Two Nd:YAG lasers operating at 1064\,nm are separately servo-locked to two vertically mounted ultra-stable cavities. The optical heterodyne beat between two cavity-stabilized lasers shows that the linewidth of each laser reaches 2\,Hz and the average frequency drift reduces to less than 1\,Hz/s.

关键词: narrow linewidth laser, laser frequency stabilization, high finesse cavity, optical clock
