Abstract

We outline what is to our knowledge the first experimental demonstration of an excited-state Faraday filter. The filter consists of potassium vapor between crossed polarizers in a dc magnetic field and operates on the 4P1/2 → 8S1/2 transition in potassium. The 4P1/2 state is populated by a linearly polarized, 10-ns light pulse from a dye laser operating at 769.9 nm. Another linearly polarized, 10-nsec pulse at 532.33 nm traverses the pumped volume of the K cell and is absorbed from the 4P1/2 state to the 8S1/2 state. The transmission of the filter is approximately 3.5% at 532.33 nm with a bandwidth of less than 10 GHz.

  14. The saturation intensity of the pump beam was estimated by measuring the pump-intensity dependence of the probe absorption. The probe absorption varied linearly with the pump intensity for smaller intensities, then became sublinear, and ultimately saturated as the intensity was increased. The absorbance of the probe beam did not change even when its intensity was increased by 3–4 orders of magnitude from the level used in the Faraday transmission measurement. This indicates that the probe-beam intensity was much lower than that necessary for saturating the excited-state transition.

Faraday filter transmission spectra near 532 nm. The top trace is the filter spectrum with the pump beam, the probe beam, and the magnetic field all on. The middle trace represents the anomalous effect with the pump and the probe beams on but no magnetic field applied. The bottom trace shows zero transmission in the filter passband with the pump beam turned off.
