    Abstract: The study analyzes a wide range of technologies generated by the creation and application of focusators of laser radiation. I give a brief review of methods for solving ill-posed inverse problems of diffraction theory, the methods of monitoring and substrate forming a diffraction micro-relief, optical systems and devices for experimental research of focusators, laser technologies and units on their basis.
