Beam pointing direction changes in a misaligned Porro prism resonator

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 misalign...

Zusammenfassung:	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.
