- Abstract
- Following the rapid advances in, and wide ranging applications of, tunable laser sources, there has been an increasing need for a simple yet accurate technique to measure laser profiles and to provide for direct wavelength calibration. Recent work at the National Bureau of Standards has demonstrated the observation of electronic transitions using the optogalvanic effect (OGE) in flames and discharges. Voltage changes are observed in a low pressure gas discharge when an exciting laser source is tuned to an electronic transition of any atomic species present in the discharge region.
