An universal algorithm of a “search for coincidence” gravitational signals with neutrino events in the 100 second window was developed with statistical estimation of the “right detection”probability (W1). The spectrum density and correlation properties of seismic perturbations in the Baksan Neutrino Observatory were measured during a quiet period of time. The “newtonian gravity-gradient noise was calculated according to the experimental data of seismic spectrum density along the main tunnel of the BNO RAS (W2). Mirrors at the CaF2 substrate formed a solid body FP cavity were tested at low temperature. Evolution of the integral optical characteristics such as finesse and contrast was monitored in the presence of optical pump 10 – 400 mW at the temperature interval 300-5 K. Observable variations did not exceed 25% (W3) A new technology for manufacturing of silicon micro resonators with the whispering gallery mode was developed. Numerical models of micro resonator coupling with other optical elements were elaborated using the software package Comsol Mutiphysics (W3). A mechanism for suppression of parametrical instability in a new generation of gravitational detectors was proposed through the selection of optimal curvature of mirrors and using resonators with sparse spectrum components. The effect of optical rigidity was recommended for enhancing sensitivity behind the standard quantum limit (W4).
