The relative change of the beam pointing direction for a misaligned Porro prism resonator is analyzed. A concept of the oscillation axis for the Porro prism resonator is introduced to find the beam direction. Expressions for the beam tilting angles are deduced. They predict that the angular misalignment in the horizontal direction will lead to beam tilting in both the horizontal and vertical directions. Experimental results obtained agree well with theory.
The lateral shift of the mode axis in a misaligned Porro prism resonator is analyzed. A method to find the tilted mode axis in a misaligned Porro prism resonator is introduced. Expressions for the displacement of the mode axis are deduced. They predict that the lateral displacement of the mode axis is proportional to the horizontal misalignment angle beta and highly dependent of the prism azimuth angle theta. Experimental results obtained agree well with theory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
