| Research Abstract |
Applying 2nd order nonlinear effect produced by the nonlinear optical crystal, we have achieved in the generation of the 8-dB squeezed vacuum. Injecting the squeezed vacuum into the dark port of the interferometer, we could reduce the shot-noise level by 2dB. This is the first practical demonstration of the shot-noise reduction in the gravitational-wave detector using squeezed light.
