Abstract

A measurement of the natural linewidth of the 401 nm 4f¹²6s² (³H₆) rarr} 4f¹²(³H)6s6p (¹P^o₁) (6,1)₇^o transition in Er I is presented. Using laser-induced fluorescence in an atomic beam, a linewidth of (36.0 plus or minus} 1.2) MHz is observed, a value that differs significantly from the accepted literature value of 28 MHz. This measurement provides an accurate determination of an essential laser cooling parameter that plays a central role in the development of novel laser cooling applications using Er atoms.
