Abstract

Fluorescence from neutral atomic yttrium is measured at the 25/22D 3/2 transition, corresponding to a wavelength of 622.26 nm. The upper level, 25/2, is excited using a diode laser operated in an extended cavity Littrow's configuration at 643.5 nm, corresponding to the 2D 5/225/2 transition. The atomic source is a hollow cathode lamp. A concurrent optogalvanic signal has also been measured.
