Abstract

Currently, the use of crystal optical systems in the scientific and technological development has increased significantly. With their help it is possible to solve the control tasks of the amplitude, frequency, phase and polarization of the laser radiation and scanning by an optical beam in space. In addition, crystal optical systems are used for spatial encoding; creating controlled spatial filters in polarization interferometers, allowing investigating the quality of processing of optical parts, geometric parameters of the laser beams, the degree of coherence of the laser radiation to a high precision. When the laser radiation is placed at the output of crystal optical systems, there appear the interference patterns, which are applied for various purposes in laser measuring devices. The construction of circuit schemes and laser devices should continually be improved to enhance their capacity, accuracy, sensitivity, reliability and service life. Providing a solution for these problems is possible upon condition of new ideas that have emerged in crystal optics and laser technology.
