title: [Experimental study of the properties of two-order FADOF at Cs 455 nm line under Nd:YAG pulse laser condition].
abstract: This paper experimentally studied some important properties of two-order FADOF at Cs 455 nm line under Nd:YAG pulse laser condition. At a selected temperature the properties of both the bandwidth and the transmission related to the magnetic field have been obtained. In this study, the bandwidth of two-order FADOF was increased linearly with the increment of the magnetic field from 200 to 700 Gauss and is obviously narrower than that of the two single-order FADOFs. The transmission of two-order FADOF was also linearly increased with the increment of the magnetic field in the same range and is lower than that of the single FADOF. Fortunately, at a slightly higher cell temperature, such as T = 160 degrees C, the transmission of two-order FADOF can reach 40%. Furthermore, it can reach theoretically up to 80% because 90% can be obtained in the case of single FADOF. The most important result in the study is that the out-of-bandwidth rejection, which is one of the three parameters, was improved from 10(-3) to 10(-5). The structure of the two-order FADOF is relatively simpler than that of the single-order FADOF.
