The tightness of optical springs, such as in GWDs, is figured out by the light power within the optical cavity. Thus, improving the resonant frequency of optical springs requires increasing the intracavity light power which, however, can result in thermally harmful results and avoid the detector from working properly.To address this concern, a team of researchers from Japan, led by Associate Professor Kentaro Somiya and Dr. Sotatsu Otabe from the Department of Physics at Tokyo Tech, established a revolutionary service: the Kerr-enhanced optical spring.
