Abstract: We performed two-color spectroscopy of the (4s(2)) (1)S(0) -> (4s4p) (1)P(1) -> (4p(2)) (1)D(2) calcium atomic transition and observed velocity-selective optical pumping in a calcium hollow cathode lamp by means of optogalvanic detection. The optical pumping signature in optogalvanic detection is compared to that of fluorescence and transmission detections. The optogalvanic technique is found to be a very sensitive method of detecting optical pumping and could be used in distinguishing optical pumping from electromagnetically induced transparency.
