Analysis of the characteristics of an optical monoblock ring confocal resonator

A sample of an optical monoblock ring confocal resonator is analyzed. It is a reflective prism made of S-TIH optical glass with four working surfaces located at the vertices of a square. One of the reflective surfaces is used to input and output radiation from the resonator by violating the effect of total internal reflection with the help of an auxiliary reflective prism. The spectral and other optical characteristics of a sample of an optical monoblock ring confocal resonator are studied. Its advantages over other types of optical ring resonators and the prospects for its application in optical sensors, in particular, in optical gyroscopes, are also considered.
