LASER RESONATOR

FIELD: quantum electronics. SUBSTANCE: resonator has bearing structure in the form of two plates carrying mirrors which are joined together through pins and provided with supports; bearing structure is set on supports installed on base at corners of plates; two of these supports are arranged on output beam axis; first support is mounted under output mirror and fixed in position relative to base; second support is installed on opposite plate and is free to move relative to base only along output beam axis; remaining supports are made for displacement within base plane. In addition, output mirror support may be made in the form of ball placed between two conical surfaces; one of these surfaces is provided on plate and other one, in base; support that is free to move along output beam axis may be made in the form of two bodies of revolution secured on plate or base and arrange so that they embrace guide mounted on base or on plate. EFFECT: improved strain resistance including stability to maladjustment caused by mechanical or thermal effects. 3 cl, 4 dwg
