The strength of items bonded by optical contact has been determined, taking into account the specifics of the production technology of helium-neon ring lasers. The variation of the bonding strength as a result of prolonged heat treatment is considered. A method is proposed for reducing the stresses that appear in the bond. A study has been made of how the difference of the thermal coefficients of linear expansion of the materials affects the stresses that appear in contact bonding. © 2014 Optical Society of America.

This paper discusses the possibilities of laser technology in operations involving the assembly of optical elements, using heat-shrink materials. It is shown that, by choosing the radiation parameters, spatial localization of the heating that is adequate for shaping can be achieved in a polymeric material but still does not result in undesirable heating of the item being assembled. A process is described that uses the proposed method to assemble an electro-optic modulator based on a DKDP crystal. © 2013 Optical Society of America.

This paper discusses the possibility of creating a piezo adjuster with passive thermal compensation elements to be used as part of a ring laser gyroscope to counteract thermal variations of the optical path length of the cavity. The dependence of the linear thermal expansion coefficient of glass-ceramic CO-115M is investigated. The paper presents the temperature dependences of the variation of the cavity perimeter when ideal and actual piezo adjusters are used. It is shown that passive thermal compensation can be achieved by varying the geometrical parameters of the piezoelectric actuator's structural elements that have various values of the linear thermal expansion coefficient. © 2011 Optical Society of America.

This paper discusses a system for adjusting the perimeter of a frequency-stabilized ring laser gyroscope. It is shown that the main error source of the gyroscope is temperature effects on the path length of the optical cavity. The design of a piezo adjuster, which is the basic element of a system for adjusting the gyroscope perimeter, is considered. The main requirements imposed on the piezo adjuster for its successful operation as part of the laser gyroscope are listed. A physicomathematical model for the piezo adjuster and a number of computer programs based on it are considered. Results are given of the numerical modelling of various designs of the piezo adjuster, including the existing design. It is shown that the output parameters of the laser gyroscope can be substantially improved by changing the geometrical parameters of the design elements. © 2011 Optical Society of America.
