A plurality of different layers of filter media are used to remove siloxanes from a gas stream. Based on an analysis of the specific gas stream to be filtered, a filter media having an average pore size enabling the preferential removal of a specific class of contaminants is selected for each different class of contaminants. The layers are arranged in sequential order such that contaminants having a higher molecular weight are preferentially removed by the first layers. Collectively, the layers define a segmented activity gradient that enables each class of contaminants present in the gas stream to be preferentially removed in a different layer, preventing removal competition between different classes of contaminants. Preferable adsorption media exhibit a relatively narrow range of pore sizes. Both inorganic adsorption media and carbon-based adsorption media exhibiting a relatively narrow range of pore sizes can be used.

The invention discloses a laser gyroscope, relating to the laser technology, the optical technology and the inertia measurement technology. The existing laser gyro uses gas gain medium. The laser gyroscope uses a solid gain medium to replace the gas gain medium, thus realizing the all solidification of the laser gyro. However, compared with atoms or ions in the gas gain medium, atoms or ions in the solid gain medium are relatively static, thus causing strong competition among bidirectional optical field modes so as to further cause the instability of the optical field. In order to overcome the difficulties of the laser gyro using the solid gain medium, the laser gyroscope utilizes the optical stimulated scattering effect of pump light and the solid gain medium to provide gains for laser fields. As the laser fields spreading in different directions depend on the incident direction of the pump light, the pump light can be used for controlling the gains of the stimulated scattering light field spreading in different directions, thus realizing the stable output of the bidirectional laser mode of the solid laser gyro. The laser gyroscope is applicable to on-ship integration of the laser gyro.
