An autonomous laser pressure meter for under water using is described. The using of optical measurement methods based on interference methods, optimization of the device design based on existing design experience, made it possible to develop and create a compact device having a high accuracy of measuring pressure fluctuations in a wide frequency range. The device can be used far from the coastline, since it provides the possibility of its autonomous operation, for which a container connected to the device, equipped with batteries, a system for collecting and storing information, was developed. Sensors outside and inside of the meter allow data correction depending on changes in the temperature of the interferometer and seawater, and an additional power interface and data port allows you to connect external devices to extend the functionality of the instrument.
