- This study experimentally confirms the long-predicted limitation of the high-power operation of the LIGO detectors due to parametric instabilities, leading to new strategies and triggering the development of new technologies to further increase the resonating power in the detectors. Martynov was in charge of controlling the LIGO Livingston interferometer and for increasing the power resonating in the arms when parametric instabilities were observed. He also contributed to the data analysis of the instability and found the reason why the unstable modes of the test masses appear at the wrong frequencies in the LIGO data acquisition system.
