Abstract

The frequency of the 0.6328-μm output of a helium–neon laser has been servocontrolled at the peak of a passband of a quartz Fabry–Perot étalon whose temperature is stabilized by means of a triple-point cell of diphenyl ether. The output of the laser is modulated by a retroreflector employing a lens and a vibrating mirror, and an error signal is detected by a lock-in amplifier. Experiments have shown the long-term stability of 1.4×10⁻⁹. The resulting frequency-stabilized output is free of modulation and capable of being used for long-path-difference interferometry.
