Radio-Frequency Stark Tuning of Optically Pumped Far-Infrared Lasers

摘要

We have directly monitored the rf Stark field induced splitting of the gain profile of the 1222 micrometer 13CH3F optically pumped far infrared (OPFIR) laser transition. The resulting data are found to be in good agreement with ac Stark theory. Comparisons with dc Stark tuning techniques shows that the rf Stark effect possesses a number of attractive attributes for frequency tuning cw OPFIR lasers, including significant increases in the tuning range and straightforward implementation.
