Abstract
In this paper, the possibilities of research and application of fiber laser sensors were presented. The technology for measuring physical parameters and improving sensitivity using optical fiber’s and laser beams was discussed. The main objectives and design of grating resonator laser sensors were defined and the focus was on their development and fabrication. The experiments performed confirm the high accuracy and performance of the sensor. These sensors can be used in medical, industrial, research and safety applications. This research is an important step towards promoting the development of measurement and control technology. In addition, it extends the range of measured parameters, enables load building and new sensor models. This research unlocks the potential for technology development and practical applications in many fields.
