Technological applications for focusators of laser radiation

The article analyzes a wide range of technologies generated by the application of focusators of laser radiation. I give a brief review of the methods of monitoring substrates and forming a diffractive micro-relief, optical systems and devices for experimental research of focusators, laser technologies and units on their basis. In particular, I analyze the use of focusators for thermal quenching (and control) of the cutting edge of the cutter in machine industry, for operational control of macroscopic defects on the inner surface of pipes in the oil industry and other applications of focusators.
