Abstract
Earth, etc.) is expected within the field of view of the receiver. A high-sensitivity and high backgroundnoise-rejection optical filter with wide-frequency tunability around the doubled Nd:YAG laser emission can simultaneously track Doppler frequency shifts and reject intense background radiation. The Stark anomalous dispersion optical filter (SADOF) is designed to provide high background noise rejection and wide frequency tunability and to operate at the wavelength of the doubled Nd lasers [1,2]. The SADOF is similar to our previously reported nontunable Faraday anomalous dispersion optical filter (FADOF) [3-5]. It may be considered as simply an addition of an electric field and optical pumping to the FADOF. In the following sections, the basic design and theoretical calculations are presented, the issues of shifting the SADOF center frequency using the Stark effect are investigated, and the calculation results for the SADOF operating at the doubled Nd:YAG laser line are discussed. These results have been used to direct the thrust of the experimental design.
