摘要：

An historic and simple experiment has been revitalised through the availability of supercavity mirrors and also through a heightened interest in interferometry as a test of physical theory. We describe our helium neon ring laser, and present results demonstrating a fractional frequency resolution of 2.1 x 10(-18) (1.0 mHz in 474 THz). The rotation of the earth unlocks the counterrotating beams. A new field of spectroscopy becomes possible, with possible applications to geophysical measurements such as seismic events and earth tides, improved measurements of Fresnel drag, detection of ultraweak nonlinear optical properties of matter, and also searches for preferred frame effects in gravitation and for pseudoscalar particles.
