Paper Abstract

Ultrasensitive interferometer measurement technique using laser response to cavity loss modulation is described. The advantages and possibilities of this method are analyzed. The model of laser displacement sensor based on cw stabilized YAG:Nd laser with intracavit.v Michelson interferometer has been built and tested.The sensitivity of 10-16 m/√Hz has been achieved in the frequency range above 40 kHz, which is close to theoretical limit determined by natural laser amplitude noise.
