Using a hollow-cathode lamp (HCL) to build a Faraday anomalous dispersion optical filter (FADOF) is a new method to realize narrow linewidth optical filters. In contrast to other atomic optical filters based on saturated vapors, which work at a relatively high temperature to maintain the atomic density, the HCL device using sputtered particles can work at a much lower temperature. In this work, a rubidium HCL-based FADOF (HCL-FADOF) working at 780 nm is established and carefully tested. With 20 mm cathode length, the transmittance can reach 29% under 18 mA discharge current and 260 G magnetic field at room temperature, which is equivalent to the performance of a saturated vapor-based FADOF (VC-FADOF) at more than 60 ∘C. This work provides a direct comparison of the performance of the HCL-FADOF and the VC-FADOF, which is of great benefit to further studies of atomic filters at normal temperature.

Radio Frequency Voltage

Transient emission characteristics of a hollow-cathode lamp driven by a pulsed current in combination with a radio-frequency burst signal are described. The radio-frequency field excites electrode vapor that is transiently produced by the initial pulsed current discharge. To evaluate the performance of this radio-frequency injected lamp; peak line intensity, line width and line stability of Cu atomic and ionic emissions are compared to those from dc and pulsed current lamps. Results indicate that the radio-frequency lamp is superior to the conventional pulsed lamp in these three factors. However, due to experimental limitations of commercial lamps under applied radio-frequency voltage, the maximum possible intensity enhancement was not achieved. Atomic absorption working curves are also compared to anticipate practical situations. The steep and linear curve obtained using the radio-frequency lamp suggests its important role in practical analysis.
