We have developed a GW detector, which is a pair of 75-cm baseline synchronous recycling (resonant recycling) interferometers. Each interferometer has a strain sensitivity of ~10^{-16} Hz^{-1/2} at 100 MHz. By cross-correlating the outputs of the two interferometers within 1000 seconds, we found h^2 100Ω_gw < 6 ×10^25 to be an upper limit on the energy density spectrum of the GW background in a 2-kHz bandwidth around 100 MHz, where a flat spectrum is assumed.}, pages = {101101--101101}, title = {Search for a Stochastic Background of 100-MHz GravitationalWaves with Laser Interferometers}, volume = {101}, year = {2008} }
