Abstract

A narrow linewidth diode laser system at 689 nm is realized by phase-locking an extended cavity diode laser to one tooth of a narrow linewidth optical frequency comb. The optical frequency comb is phase-locked to a narrow linewidth laser at 1064 nm, which is frequency stabilized to a high-finesse optical cavity. We demonstrate the magneto-optical trapping of Sr using an intercombination transition with the developed laser system.

摘要

通过将外腔二极管激光器锁相到窄线宽光学频率梳的一个齿上，实现了波长为689 nm的窄线宽二极管激光系统。该光学频率梳被锁相到波长为1064 nm的窄线宽激光器上，该激光器的频率被稳定到一个高精细度光学腔上。我们使用所开发的激光系统，通过一个跃迁组合实现了锶的磁光阱捕获。
