Several types of laser-­interference instruments for measuring variations of hydrosphere’s pressure are reviewed in this article. Instruments’ frequency range is from conditionally 0 Hz (unbounded in principle) to 1000 Hz with accuracy of 1 mPa. Some of the results of using these laser-­interference systems for recording vibrations and waves in the infrasound and sound ranges are briefly discussed.
